Thanks so much! Another question... (sorry I'm new to this site)
My MacBook Pro (Late 2011) is running extremely slow. It's super laggy when I do anything, and I get the spinning color wheel a lot. There is a delay when moving between applications and within an application. This issue came about all of a sudden; I have never had issues before now.
I have Yosemite, and it is up to date (Version 10.10.2). I don't have time to take it somewhere to get it looked at b/c of school and fast approaching deadlines. I have been getting some notice that my "Java runtime environment" is out of date. But when I follow the link to to website, and update like it says, I still get that notification so I've stopped updating it. Idk if this has anything to do with that or not. I cleared my browser history, cookies, etc. And I have emptied my trash.
I have a midterm in two weeks, which I need my computer functioning normally to take it.
Any feedback is appreciated. Thanks in advance!
If you have never done any disk maintenance/cleanup, that could be one of the issues you are having. Also, if the internal hard drive spins at only 5400 rpm, that also can be a detriment. Here are a couple of things you can try:
1. Hopefully, the (invisible) Recovery HD partition is on your internal hard drive. If it is, you'll see it when you hold down the Option key on booting up your Mac. Assuming the Recovery HD partition is there, you can double click on it, and it will start up. From there, you can use Disk Utility to 1) Verify and Repair Permissions, and 2) Verify and Repair the disk (do that at both "levels", ie, at the Volume and Partition levels).
2. Download, install, and run the excellent freeware program Onyx. You can get it from the second link on this page:
http://www.titanium.free.fr/onyx.html
Use that program to perform some basic maintenance and clean up of your hard drive.
If those two products do not help that much, then you'll need a more robust Disk Maintenance/Repair program. The two excellent ones are Disk Warrior (
