Apple's Boot Camp software now allows users to install Windows 10 on supported Mac models with the OS X Yosmite, the most recent iteration, installed. An ISO file of the 64-bit version of the.
How to maintain a Mac 1. Make redundant backups, keeping at least one off site at all times. One backup is not enough.
Don’t back up your backups; all should be made directly from the original data. Don’t rely completely on any single backup method, such as Time Machine. If you get an indication that a backup has failed, don't ignore it. Keep your software up to date. In the App Store or Software Update preference pane (depending on the OS version), you can configure automatic notifications of updates to OS X and other Mac App Store products. Some third-party applications from other sources have a similar feature, if you don’t mind letting them phone home.
Otherwise you have to check yourself on a regular basis. Keeping up to date is especially important for complex software that modifies the operating system, such as device drivers. Before installing any Apple update, you must check that all such modifications that you use are compatible. Incompatibility with third-party software is by far the most common cause of trouble with system updates. Don't install crapware, such as “themes,” 'haxies,' “add-ons,” “toolbars,” “enhancers,' “optimizers,” “accelerators,” 'boosters,' “extenders,” “cleaners,” 'doctors,' 'tune-ups,' “defragmenters,” “firewalls,” 'barriers,' “guardians,” “defenders,” “protectors,” most “plugins,” commercial 'virus scanners,” 'disk tools,' or 'utilities.' With very few exceptions, such stuff is useless or worse than useless. Above all, avoid any software that purports to change the look and feel of the user interface.
The more heavily promoted the product, the more likely it is to be garbage. The most extreme example is the “MacKeeper” scam. As a rule, the only software you should install is that which directly enables you to do the things you use a computer for — such as creating, communicating, and playing — and does not modify the way other software works. Use your computer; don't fuss with it. Safari extensions, and perhaps the equivalent for other web browsers, are a partial exception to the above rule.
Most are safe, and they're easy to get rid of if they don't work. Some may cause the browser to crash or otherwise malfunction.
Some are malicious. Use with caution, and install only well-known extensions from relatively trustworthy sources, such as the Safari Extensions Gallery.
Never install any third-party software unless you know how to uninstall it. Otherwise you may create problems that are very hard to solve. Beware of malware. Malware is malicious software that circulates on the Internet.
This kind of attack on OS X used to be so rare that it was hardly a concern, but it's now increasingly common, and increasingly dangerous. There is some built-in protection against downloading malware, but you can’t rely on it — the attackers are always at least one day ahead of the defense.
You can’t rely on third-party protection either. What you can rely on is common-sense awareness — not paranoia, which only makes you more vulnerable. Never install software from an untrustworthy or unknown source. If in doubt, do some research. Any website that prompts you to install a “codec” or “plugin” that comes from the same site, or an unknown site, is untrustworthy. Software with a corporate brand, such as Adobe Flash Player, must come directly from the developer's website.
No intermediary is acceptable, and don’t trust links unless you know how to parse them. Any file that is automatically downloaded from the web, without your having requested it, should go straight into the Trash. A web page that tells you that your computer has a “virus,” or that anything else is wrong with it, is a scam.
In OS X 10.7.5 or later, downloaded applications and Installer packages that have not been digitally signed by a developer registered with Apple are blocked from loading by default. The block can be overridden, but think carefully before you do so.
Because of recurring security issues in Java, it’s best to it in your web browsers, if it’s installed. Few websites have Java content nowadays, so you won’t be missing much. This action is mandatory if you’re running any version of OS X older than 10.6.8 with the latest Java update. Note: Java has nothing to do with Java Script, despite the similar names. Don't install Java unless you're sure you need it. Most people don't.
Don't fill up your boot volume. A common mistake is adding more and more large files to your home folder until you start to get warnings that you're out of space, which may be followed in short order by a boot failure. This is more prone to happen on the newer Macs that come with an internal SSD instead of the traditional hard drive. The drive can be very nearly full before you become aware of the problem. While it's not true that you should or must keep any particular percentage of space free, you should monitor your storage use and make sure you're not in immediate danger of using it up. According to, you need at least 9 GB of free space on the startup volume for normal operation. If storage space is running low, use a tool such as to explore the volume and find out what's taking up the most space.
Move seldom-used large files to secondary storage. Relax, don’t do it. Besides the above, no routine maintenance is necessary or beneficial for the vast majority of users; specifically not “cleaning caches,” “zapping the PRAM,” 'resetting the SMC,' “rebuilding the directory,” 'defragmenting the drive,' “running periodic scripts,” “dumping logs,” 'deleting temp files,' “scanning for viruses,” 'purging memory,' 'checking for bad blocks,' 'testing the hardware,' or “repairing permissions.” Such measures are either completely pointless or are useful only for solving problems, not for prevention. Let go of the Windows mentality that every computer needs regular maintenance such as 'defragging' and 'registry cleaning.' Those concepts do not apply to the Mac platform. The very height of futility is running an expensive third-party application called “Disk Warrior” when nothing is wrong, or even when something is wrong and you have backups, which you must have.
Disk Warrior is a data-salvage tool, not a maintenance tool, and you will never need it if your backups are adequate. Don’t waste money on it or anything like it. One thing I was surprised to find after buying my first mac (iMac last month) is how bizarre and seemingly incomplete the 'uninstall' procedure is for OS X. I'm the type of user with Windows who would uninstall a program, then go hunt for any left behind folders. Over the years uninstallers have improved immensley and they get rid of everything 95% of the time. But with OS X, you just drag and drop the main icon into the trash, which at first I thought was BRILLIANT, but then I found that almost every piece of software left all their main folders behind, eating up space on the hdd.
I found a youtube video that shows how to manually go in and keep things clean after 'uninstalls', but I didn't think this was necessary on the Mac side of things. Over time wouldn't you need a proper way to clean things up and prevent the OS from slowing down (and losing hdd space?). I work at a Computer repair shop in Naples FL. So, that means - straightaway - you're not an average user, right? But still as someone who has to clean up adware I'm sure you know of the safe, free alternatives for that job, including Apple' own - also free - instructions. But again, I will offer this for people's consideration: And how come the folks who recommend always have very few points, and the folks who advise against have very many? Coincidence that.
Can you explain why all the experienced users on this site recommend against this app and its ilk? Anything to do with experience? Just wondering. I having been using Clean My Mac 2 for a few months and accepted the free upgrade to Clean My Mac 3.
It works well for me and my son and I am happy with my purchase. Since it hasn't been very long, I will post again if there seems to be trouble. The upgrade has several new features and I am just getting around to trying them. When I downloaded it I did so following the advice in an ebook called. I bought that book because my upgrade to Yosemite did not go well, I wanted to 'take control,' or try to, because my computer was not working well after the upgrade. After running its tasks my computer worked better.
I also used a product called Cocktail. That product also seemed to help.
Both were recommended in the e-book. Sometimes cocktail has issues since I installed Clean My Mac 3 and I thought perhaps they were conflicting when I stumbled on this conversation.
Before I bought it, I spent a lot of time searching these forums and the web - searching through forums is for me an alarming time sink. There is a lot of disagreement. One feels the risks of taking one or another person's advice and judging without being able to test or understand quite what is happening. I dislike this feature of contemporary life. I am not a 'power user' nor could I find the time or interest to become one.
I am more than weary of devices that don't work quite right. Until recently my Apple devices were a welcome exception to the general crumminess of things - I have used Apple computers since I had a 512K in college. In the end, I bought the book above and decided to follow just one person's advice as a means of keeping things simple.
I am glad I did, although i know problems will still occur. And there are just too many variables for me to control, especially given the amount of time it takes from things that interest me. I appreciate that the more experienced users who have posted in this thread warn against using Clean My Mac and other third party utilities. As others have said one person's experience is not generalizable and I speak only for myself (and my very young son whose computer I maintain.) Perhaps my computer would have recovered performance on its own or a quick lesson from a power user would have worked better.
I promise to post again if there is trouble. So far, Clean My Mac 3 works a treat and I am grateful for it. I hope my experience is useful to the OP.

Don’t waste money on it or anything like it. I know this is a little late but several things here. One there is NO ' as far as I can tell; CleanMyMac2 is latest in that line. Second, let's be honest here, the software Apple provides for maintenance is bare bones at best when it exists.
Couple that with people who have no idea on how to write programs for the MacOS and have the program drop files all over the hard drive as if they were on Windows and you have a problem. So there are there are a handful of “cleaners,” 'doctors,' 'tune-ups,' etc that are useful: TechTool Pro (which at one time was part of the Apple Care package) and the aforementioned CleanMyMac2 being the more bang for your buck ones.
Third, if you like me have moved your files form Mac to Mac over the years you are going to have files that will cause weird behavior in the OS. CleanMyMac2 was able to find an old OS X extension I didn't even known I still had and it removeal stopped some really flaky behavior of the OS. CleanMyMac2 doesn't do 'damage' as long as you use it intelligently. It is a tool and like any tool it can be misused and cause problems as a result.
The claim 'There is nothing it can do that you can't do yourself, for free and more safely.' Yes the Unix under the MacOS hood is powerful but unless you really know what the sam hill you are doing you can really mess things up. Apple's Disk Utility is still very limited compared to TechToolPro or even the one trick pony DiskWarrior in fixing what find and it still flags stuff that really aren't problems and more you have to fiddle to fix an issue that some third party software can fix in like 10 minutes in the more it it is costing you in terms of actually using your computer. The point is there is no such thing as 'free' with DIYS. I have never had it do any damage to a system. With the rise in malware and adware on Macs cleanup programs are becoming necessary. Most can be simply dragged to the trash but there a quite a few that totally hijack all the internet browsers in the OS.
Resetting the browsers and dragging the apps to the trash does not resolve the problem. I have had to use adware removal tools on at least 15 macs in the last 3 months and it appears to be an increasing problem. I work at a Computer repair shop in Naples FL. There actually is a Clean My Mac 3 beta that just came out but this only existed a few days ago. I work at a Computer repair shop in Naples FL.

The backup of the upgraded 10 partition was a sensible precaution because I had no idea that the clean install was going to work so needed to be able to revert the partition to my backed up image. Be sure to deacticate and uninstall any apps that will need to be installed and activated. It's important to deactivate before the clean install as there may be a license seat limit on some apps, e.g. So if not deactivated then the seat is lost but this can be remedied by contacting Adobe chat (I know this for a fact as I have had to do this) – Jul 10 '16 at 21:31.
A different user recently posted a similar question on. Since my answer was accepted as correct, I will repost it below. The Basic steps to install 64 bit Windows 10 are as follows. I assume here that your current configuration is the default 'Out of the Box' OS X installation. Download the correct Boot Camp Support Software for your Mac.
Transfer these files to a FAT formatted flash drive. For your Mac, use the same software as for a 64 bit Windows 7 installation. These files can be found at. Use the Disk Utility to reduce the size of your OS X partition.
In the empty space, create a FAT formatted partition with the label BOOTCAMP. Burn the Windows 10 iso file to a DVD. You can use the Disk Utility to do this. I always use a RW DVD. This takes longer to burn, but is reusable.
Restart the Mac with the DVD in the optical drive. Hold down the alt/option key and select the DVD icon with the label Windows. Install Windows to the Boot Camp partition. You will have to tell the installer to reformat this partition as NTFS. DO NOT CHANGE THE PARTITIONING DURING THE INSTALLATION PROCESS. At some point during the installation, the computer will reboot. When it does, it will boot to OS X.
This is to be expected. Go to System Preferences and instruct OS X to boot back to Windows.
The installation process will continue. After the Windows installation has completed, install the Boot Camp Support software stored on the flash drive. To accomplish this, you will have to right click on the icon and select Compatibility Mode. I do not consider the process to be that difficult. The most challenging step is creating the FAT formatted partition labeled BOOTCAMP. If something goes wrong, you are in danger of loosing data on your OS X partition. I have an 27' Imac 2011, which according to Apple is not supported for Windows 10 install.
I just walked through the steps of Bootcamp 6.0.1, downloaded the Bootcamp support files, created the Windows partition in Bootcamp, inserted a DVD of the W10 x64 ISO that I downloaded from MS and followed the procedures. The only problem I encountered (eventhough I was prepared for more.) was that I had to get a USB wired keyboard and mouse during the installation steps. However the install as such went smooth and when finalized the Bootcamp support drivers loaded nicely. I had to pair my Apple keyboard with the system. After that everything including sound, Bluetooth, graphics and what not worked like a charm.
Since after build 1511 of W10 you don't have to upgrade from 7 or 8.1 to get a free upgrade, you can do a clean install instead and register with a valid 7, 8 or 8.1 license key, for me that worked great. So when Apple states that my Imac 2011 is not supported for W10, I guess it's currently more of a statement than a fact.
I guess they mean that they don't put any further additional efforts into keeping it compatible onwards whenever MS decides to change W10 system logic. However since W10 is really a polished W8.1, with basically the same 'under the hood' logic, any Apple Bootcamp supported Mac up to W8.1 Mac's (like my Imac 2011) is perhaps likely to support also W10, even if Apple doesen't want to state that.
