Sorry Mac fans, but I GIVE UP!!! I've simply had it with the poor quality software that Apple is releasing. Xcode is an abysmal mess that hogs up gigabytes of memory. I have a multi-portioned OS X setup and the things I'm able to do with Mavericks and earlier OS X versions are easy, but with El Capitan, it's a food fight. Todays source of irritation is Time Machine. I keep separate backup drives for each OS X version I need to maintain and on each of these I also backup our source code volume. On anything earlier than Yosemite I can backup not only the OS but the source code partition in a reasonable amount of time. A full backup of both portions (OS and our source code partition) is about 2 hours, and an incremental backup is done in minutes. On El Capitan, this was looking like it was going to be at least an eight our excursion. I finally terminated the backup process because I don't have time to wait around for it to complete. I should add that by Time Machine's own reporting, the amount of data to be backed up was about 17GB. When Xcode launches it erratically starts running socketfilterfw process which can eat up to 800MB and keep the CPU running at full tilt for about 15 minutes. Safari web processes often reach over 1GB of memory and bring the system to it's knees. Even Mail can cause excessive memory use. This is ridiculous. If I have any say in it, I think our company should simply stop developing for Macs. The "it just works" statement should be replaced with "it's diarrhea-ware". This operating system is at best a bad joke. I've had it!!!
