MacBook Pro Retina (late 2013). Recently getting spinning wheel in Safari. Pages don't often fully load.

Had MacBook (late 2008) with 2GB RAM that ran great for 4/5 years. I ran JMP, GIMP, other high usage programs often and never had any problems.

I haven't been running heavy duty programs, and I can't figure out why my memory is maxed out. Is this even the problem?

Took me a few tries to even post this. TIA for any help.

How do you know that your memory is maxed out? Are you just assuming that's the problem?

Open Activity Monitor (/Applications/Utilities/Activity Monitor.app) and click on the memory tab to see which applications are using large amounts of memory.

Yeah, checked activity monitor to see how much I was using. That was kind of my first step. ~7.9/8 being used. I quit programs and it goes to 7.6ish then I'll check back later and it's back at 7.9. Doesn't make sense to me.

Finder takes up almost 250MB, mail takes up about 200MB, and one open tab of salari is the next largest. I quit all of my programs religiously, so I don't really get it. Tons of little stuff that I don't know about (embedded stuff I guess?) consume the rest.

I have a ton of space on my hard drive. Not that it's an issue.

This sounds like my computer after letting a friend use it.

He "accidentally" downloaded a rootkit. It drove me nuts trying to figure out what was going on.

Don't know if that's your problem, but it couldn't hurt to check it out.

Basic question but have you rebooted?

My guess is Shockwave or Flash.

You can try opening a bash shell and run the "top" command. When it opens press "m" to sort by memory usage. This might tell you what is using so much memory?

Same problem as of late with my 2013 model as well. Fully loaded with ram. Problem appears to be a safari issue with this recent yosemite update = hot garbage. Hopefully a future update will fix it.

This is what slows down my MacBook. Only appears to happen within FireFox.

No, I actually haven't. I've let it die a few times but have not manually rebooted. Need to give it a shot.

Thanks, I'll check it out today. Not even sure what a Rootkit is.

See, I always used "top" in terminal on my old MacBook. It was essentially the activity monitor and was easy to force quit non responsive programs in there. On my new MacBook "top" does not list all of the running applications. Not sure why.

I think the problem is solved. I upgraded my software again today (already had newest OS, but updated to 10.10.3). Still had spinning wheel. Went into activity monitor and killed everything titled "mdworker" in terminal. Then I restarted my laptop, held down shift when it rebooted, and everything seems to be running great.

Hope it lasts, and thanks to everyone for the help.

Check your activity monitor to see what is taking up ram and cpu. Something doesn't sound right..

I have the same rMBP and I haven't had any issues running many tabs on safari, chrome, plus a music or photo editor all while running virtual machines for SQL and visual studio. The memory management on these things is impressive.

eta: Ive had issues with firefox though, as others have mentioned. Usually it is related to extensions like ad block and all kinds of other crap.

mdworker is a background process that scans files and creates metadata for indexing (for Spotlight searching, etc.).

Sounds like mdworker had a problem with a certain file or something and it caused it to crash and eat up memory. Killing it like you did usually fixes the problem.
