I have a 2011 21 inch iMac with 8gb ram and a 2014 macbook air 13 inch with 4gb ram. My iMac came with lion which was probably the smoothest os i have ever run - don't remember a single crash. However as I upgraded to mountain lion , maverick and now yosemite the system is clearly more unstable and crashes have become more frequent. I love the iCloud drive, sms relay and continuity features of yosemite and don't want to go back but I find that apples OS is definitely more buggy as they go to yearly releases. My iMac with 8gb quad core is more laggy than my 4gb macbook air . Preview in particular seems to crash frequently requiring system reboots. I think for OS X apple should focus on the user experience and stability for the next few years instead of rushing out newer versions every year. I know that I can do a clean install but thats not the point. The point is apples OS updates should run smoothly without having to do a clean install everytime!! Having said that , my iphone 4 when it came with iOS 4 was much more stable than my iphone 6 plus with iOS 8.1
Memory clean? Why are you doing that? You do know that since Mavericks the OS tries to grab all the memory it can, quite deliberately? Any unused RAM you have is wasted RAM, so the OS doesn't waste it.
Do yourself a favour: Turn off memory clean, and keep an eye on Memory Pressure in the Activity Monitor instead. If your memory isn't under pressure, you don't have a RAM issue. Interfering with the way that the OS handles memory (e.g memory clean) might itself be an issue.
There are plenty of background processes running - especially right after an OS upgrade - that require memory, not just a couple of open apps you might see on a desktop.
Ive has way too much power at Apple. I don't think Jobs would have let him touch OSX.
Why is this guy doing software? Judging by how hideous Yosemite is, he never should have been let anywhere near it.
Safari looks ridiculous, like a third grader designed it.
His obsession with thinness at the expense of functionality is so annoying I wish Apple would just get rid of him already.
Fortunately, noone's job at Apple depends on (steve333) liking them.
The Mac doesn't completely boot up before allowing you to log in. . .if just boots the log in screen and then you've to enter the password and then wait for boot. Before you could...
That was always the case if you have FileVault turned on.
You probably turned it on without realising it.
With FileVault turned on, your Mac HD is encrypted. Only your password can decrypt the data.
Which means only after you login, the boot up and decryption processes starts.

Treat it like a new extended beta test program; it comes out 12 months early, they work on it on a regular basis and, when its finally knocked into shape and is as stable as its ever likely to get, they call it 10.10.5 mark it as done and move onto 10.11.0
That's when you upgrade from 10.9.5
You run that 10.10.5 for a year (free from need for regular boring downloads of point updates and any of the hassles other folks are getting) and then repeat the process with 10.11.5
You still get a new OSX on your machine every year; the only difference is you get a stable one with all the bugs shaken out, and that all your software has finally got round to fully supporting
Easy
The little bug where you click on something - but it doesn't register the click. . .so you click again is EXTREMELY frustrating.
