Indeed, I actually have a ridiculous and frustrating ongoing problem, apparently insoluble, where no matter how many times I update an app that appears under &quot;Updates Available&quot;, it will reappear after seemingly successfully updating.<p>So I&#x27;ve installed the identical copies of XCode, iMovie, The Unarchiver, etc., etc., over and over. Then entries with identical versions and release dates very shortly after reappear in the list.<p>This, on top of countless other frustrations (such as transferring my MBP from my home &quot;battlestation&quot; to offsite causing full system crashes about 1&#x2F;3 of the time, Time Machine not working properly with my NAS setup, WiFi overheating&#x2F;malfunctioning FUBAR right after upgrading to Yostemite, various other minor random things breaking and annoyances, and so on, including the generally arrogant attitude Apple takes of its customers and developers), I&#x27;ve had enough. Next computer I&#x27;m running back into the arms of Linux, because the main argument against it is that Linux eats up a lot of time configuring, but I&#x27;m already wasting way too much time dealing with my OS&#x27; issues, one that ostensibly &quot;just works&quot;, so I might as well get the benefit of having a working, productive development system at the end of it.
