Like many of you, I am very leery of upgrading computers to mew operating systems. I always try it after a few months go by and only on one computer before switching all computers. There have been OS that only one computer was upgraded because of all the glitches and crashes.
My background
I have 5 Macs, 2 iPhone 5, 1 iPad and 1 iPad Mini Retina. I am a real estate photographer, web designer, and I design marketing ads for real estate besides doing SEO and social media. Because of the real estate business, I need to access real estate files, so cloud storage is also a major key.
How I Developed My Hypothesis
I recently bought 2 new computers. The MBP 15" was top of the line, 1 Tb flash storage, i7core processor, and 16 Gb of memory. The other computer was added mid December with Yosemite. I use all iWork apps,
Aperture, Compressor, Final Cut, and RapidWeaver for web design and plug-ins that complement these apps and programs. I found that the new computers worked fine. why doe these computers work OK but the others don't?
"Cleaning" My Macs - What I found out...
I always had problems no matter how long I waited to install a new version of Mac OS. My research showed that most of us had some problems but others did not and there were those who had no major problems at all. I hypothesized the following:
1) "Cleaning" programs such as Mac, "cleaned" files that may have been necessary for a particular program and when the OS tries to access it, there is a crash. So I stopped using MacKeeper. After, completely wiping and re-downloading the operating system OS 10.9 and loading each of my programs and plug-ins I needed manually or through the App & iTunes stores, I have not had any problems for 6 months with any program. I did this with two of my three older computers, Macbook Air and Mac Pro mid 2012. The only major change has been not using MacKeeper.
2) If you are a basic user, (email and internet) you probably won't have major problems but I even found the Finder became corrupted with a basic user. It was slow and crashed all the time.
3) Each program may create it's own set of glitches, that is why we may not all experience the same issues. It can become a major problem when we upgrade over the OS that has a missing file that does not present a major problem in the current OS but in an upgraded OS issues arise.
4) After having all the problems with the OS upgrades, I have stayed away from Microsoft Office, Word, Excel and Powerpoint.
Conclusion:
I only recommend switching if you absolutely need to take advantage of new features. I have started upgrading because I need the flexibility of working with a cross-platform & cloud environment. I use iWork programs, and until I upgrade, I have lost the ability to access my cloud files.
Since the computers are no longer being "cleaned" by MacKeeper, I found that I could migrate each computer using TimeCapsule without any problems. Some programs do need to have the plug-ins re-installed.
) 2011 MBP and I have had no hanging in Safari, no Bluetooth issues other than the usual of having to reconnect my Jambox on occasion, which I have always had to do, and zero awake from sleep issues in the last 5-6 days since both new iMac and MBP have been running Yosemite.
gimmick is the cause of the difficulty in distinguishing greyed/unavailable menu options from black/available menu options in the dropdown menus in all applications. Not enough difference in shades between the grey and the black. Never had this problem in Mavericks or its forebears.
