This wikiHow teaches you how to prevent your Mac computer from freezing and displaying the rotating color wheel. While there are some steps you can take to fix a currently frozen Mac, outright prevention is the best solution. OnyX for Mac version number 2.2.8b5 is the software version tool that provides the complete multi purposeful start up disk management tool efficiently designed exclusively for the Mac operating Intel, Mac OS X 10.6 Program Release Status: Minor Update Program Install Support: Install and Uninstall.

I have recently upgraded to Sierra. I also am running Parallels 12 and Windows 10. Since the upgrades my computer, a late 2011 MacBookPro, is either running very slow, or freezing. I spend a lot of time restarting the computer to try to get it going. Firefox frequently does not work. I have the impression that the computer is totally overloaded, the fan is almost always going full pelt. Should I get rid of Windows 10 and Parallels 12, and replace my current Office suite with Office 365 for Mac?

I must say that I am rather fed up at the moment as I am wasting a helluva lot of time on the simplest operations. Grateful for your help Gonzalez49. I would say that is an excellent first step, to get rid of the Windows Partition created by Parallels.

Just out of curiosity, why do you have a Windows partition? Also, Office 2016 (via a direct purchase of the package, or the Office 365 subscription) should work fine. I believe Microsoft has done a super job in terms of making all the Office software across all platforms as compatible as possible. By the way, Apple issued its second update to Sierra, OS 10.12.2, last week. You can get the Combo Updater from here: Additionally, from what OS did you upgrade from, and did you upgrade 'in place'? And, have you done any disk cleanup/maintenance/repairs?

Finally, are you making backups of your Mac partition to an external device? First of all, get rid of CleanMyMac! It does more harm than good.

Step 1: Like the majority of Excel shortcuts, you must start on an active cell. If we take a look at our Excel Skin we will see “strikethrough” lands on the “X” key, and is printed in green text. Shortcut for strikethrough in excel on mac. Step 2: Now that we have a cell selected we can execute the “strikethrough” shortcut. What is nice about the “strikethrough” function is you can apply it to cells that do not have any data yet, so if you enter data into those cells they will automatically have the strikethrough formatting applied to them.

There are better products out there, and some of them are free. One of the best is the venerable, solid, and well-reviewed software entitled Onyx.

Another individual, in another thread, recently had issues restoring from a Time Machine backup, in that some 'stuff' that was restored caused issues. So, that individual needed to revert to a clean installation of the Mac OS in order to get his machine to run again. I'm not saying that your backups are necessarily 'bad', but it might be best to first do as much disk cleanup as you can on your own with the Mac partition, and then do some more with some other, more solid tools. A combination of the excellent freeware product called Onyx and Disk Utility is a good first attempt, but you might want to consider a more robust disk cleanup/maintenance/repair product like either TechTool Pro (which does a lot), or Disk Warrior. I run, in sequence, Onyx, TechTool Pro, and then SuperDuper! (for my backups) once a week for both of my Macs, and my backups are as 'clean' as they can be.
