When a new version of an operating system is released, like the recent iOS 8 and OS X Yosemite updates from Apple, the first question we should ask ourselves is, "should I upgrade?"
As architects, we enjoy exploring and using all the new and useful features that these updates offer. Though the temptation is strong, I caution against doing so right away.
I would recommend that you first update a second Mac and use that as a test machine. Make sure to run all you apps through their paces and check with each software developer on compatibility with the new OS's. Also, never, and I repeat never upgrade your main Mac while you're in the process of completing construction documents or before giving a presentation. Like texting while driving, it can wait.
Have you upgraded to iOS 8 and or OS X Yosemite? Have you experienced issues or has it been smooth sailing? Let us know in the comments.
