Here are just some of the error messages I’ve seen since installing Yosemite last Thursday And many other apps that never crashed in Mavericks are crashing for no apparent reason in Yosemite. For example, Dropbox has always been well-behaved, but it crashes regularly under Yosemite. And while I haven’t encountered any deal-breakers in iOS 8 so far, my upgrade to Yosemite has been a little sketchy. I installed Yosemite and iOS 8.1 within minutes of their release, ‘cause that’s my job. If you depend on your Macs (or iDevices) to earn a living, a post-upgrade snafu could cost you hours or days of productivity. That being said, my experience has been that some people have some issues with every single point zero release I can recall.

While most such upgrades go smoothly most of the time, you’re much more likely to encounter unpleasant surprises when you install the first release (also known as the “point zero” release) of a new operating system. So I encourage you to wait a week or two before you pull the trigger on any operating system upgrade. If an iOS upgrade breaks your favorite app, you’re stuck until Apple or the developer push out an update. iOS is worse - there’s just no turning back.

But as eager as you may be to sample their improvements, don’t install either until you read what I have to say.įirst things first: Apple hates when I write a column like this one, but I write one like it pretty much every year for some operating system upgrade, or in this case, two operating system upgrades.
