MacBook Running slow

Thanks so much. I had been having slowness issues for some time now. Came across your post, tried it and I think it fixed my problem. It's only been a few hours and I can say my Macbook seems to be back to normal.

The original issue seems like an intel type issue of NOT clearing cache properly even on reboots, which do not allow the capacitive nature of dynamic (and even static) RAM to empty, even when "shutdown" if the power is still connected dynamic and static RAM can still hold data!

Add this is by way of possible explanation as to why the solution works!

ciao

This technique is still working!!! Just helped me too 🙂. Thanks!!

I've been having the same performance problem with my Mac, and found your response on this page. I've been laughing at your "Dark Magic" response all morning! Thanks so much for filling my Friday morning with laughter! :-)

Just tried this. My laptop is working much faster!!

I checked the "Activity Monitor" for CPU % usage. Before the "trick" Firefox was using 60% CPU time. After it was only 10%. Good stuff. Thanx

Fabulous! Thanks plenty AppleFixitGuy. Your screen name is sure fitting!!!

I have a mid 2009 Macbook pro that has made me an Apple convert! All of the sudden it runs like Windows Vista! I have 8g ram and 1t hardrive that is 3/4 full. Apple support to there credit has spent many patient hours with me to no avail. Basically the prognosis is my machine is too old. I except that. But there is no way in **** I will buy another Macbook Pro that may take a crap overnight and then need to be replaced. Bought top of the line last time and won't be fooled again. Sure MS machines are lousy, but I can buy 5 to 10 of them for the price of a top of the line MacBook Pro. Good Riddance " EL CRAPITAN! " !

I have 3 2009 machines -- 2 MBPs and an iMac -- all on El Cap, all running very well. One did experience a slowdown, the others never have. On the one that did, I went to disk utility, and ran "First Aid". Slowness gone! Your disk is pretty full, and if you've never cleaned it up, that might help. Also, if you don't totally shut down once in a while, things can seem to get sticky. If you haven't tried it, do a full "cold" shutdown, including removing the battery if you can. Wait at least 5 minutes, the put the battery back in, and boot up.

If it's just Safari, try a Safari reset.

If none of that helps, try a "genius bar" appointment. The online and phone support form Apple is probably the best there is, but there's nothing like a sharp nerd looking at your machine.

Good luck.

5 years and your computer is tagged "antiquated", after 7 years (such as my mid 2009 Macbook Pro) and your computer is considered "obsolete", Apple Genius bar no longer looks at "obsolete" machines and Apple carries no parts for them. I agree Apple phone support is tremendous. These discussion are also great. I will remove the battery and appreciate the suggestion. If that doesn't help then I will do a "Factory" reset. I have already reloaded the operating system to no avail. I have loved this machine, though it costs an arm and a leg. Hence my desire to keep using it. I would not hesitate to buy another Macbook Pro per se, but I am very hesitant to buy El Capitan! Cheers!

I had the MB replaced on my 2009 machine in June 2014 via an Apple Genius Bar appointment. Still running fine today with El Cap. I've never had the Genius Bar guys turn me down. But, OWC has a lot of stuff for older Macs, so you might check there. I bought some memory there and it worked great. The have great instructions, tools, and parts for machines Apple no longer supports.

This worked for me as well on OSX El Capitan. I have a MacBook Pro, Late 2011, which has been gradually becoming unbearably slow. The steps provided by AppleFixitGuy seem to have worked like a charm. Thanks for the solution!

What exactly does that do? What "problem" does it "fix"? As in what's the cause of the problem?

Had the same issue and your fix helped. Amazed that such a simple procedure sped up the processing. Thanks!!

I tried this, now my computer is just a black screen after restarting
