OS X V10.7 Lion :: Computer Is Very Slow After Lion
Mar 8, 2012
I have an Intel MacPro dual core with 8gb of ram and over 300mb available in disk, I just finished installing Lion and suddenly the computer started running very slow. When I finished the installation the computer was running pretty well and I really don't know why is running slow like this. I checked the system and everything looks fine, I mean, plenty of ram memory, over 4gb available, plenty of space in my hd and resources seams like quite a bit of usage. Is this due to spotlight doing indexing?mI was wondering if this is the probable cause of this drop of speed.

when I upgraded to lion (I think). I also run VMware fusion with windows 7 so maybe a virus? I ran disk utilities, followed suggestions on these communities to no avail. Our IT person and then apple support told me I should replace the hard drive. So I did. I played around a little bit and everything seemed good. Then I did a full restore from time capsule and everything is going downhill again.

It is frequent that the computer delay to an input takes several seconds. I find this in both my computers a mac mini and a macbook pro with LION, particularly with the wireless touch-pad.

Over the past month Lion has been crashing, running slow and freezing constantly.\Â I am not used to having so many PC type issues on my Mac. I have done Disk repair in utilities and removed unecessary programs at start up.Â

I just upgraded to 10.7.3Â from 10.6.8 on my Mac Pro (3,1). Since then, I have had to wait a couple of minutes (with a spinning beach ball) just to print. During that time, the print dialog box is frozen. It doesn't matter whether the output is a network laser printer, a USB inkjet or even a PDF file. And it doesn't make a difference with the application. I have tried using generic printer drivers, reinstalling lion from the recovery drive, using DiskWarrior and Disk Utility to repair the drive, repairing disk permissions and using the combo update. I originally installed Lion from the App Store. I have a Macbook Pro with Lion that has no trouble printing over Air Port Extreme on the same laser printer.

In Excel for Mac (Office 2011), simple copy-paste operations can take a few seconds even with small files with no complex content. Sometimes Excel files also take very long to open.

I upgraded my wife's Late-2007 MacBook White to Lion and now sleeping and shutdown take a very long time. On Snow Leopard, sleep and shutdown was instantaneous! Close the lid and BAM! done. Selecting shutdown on the menu and BAM! turned off.Â
Now, after upgrading to Lion, they take a really long time. I deleted the shutdown log, turned off the computer and then turned it back on and checked on it. All processes go in less than a second, but com.apple.securityd doesn't exit at all and has to be killed as I see this message on the log:Â
19988665    1 com.apple.launchd                          28 com.apple.securityd                     Exit timeout elapsed (20 seconds). KillingÂ
One of the last messages on the log is this one:Â
19992024    1 com.apple.launchd                           1 com.apple.launchd                       System: Userspace shutdown took approximately 20 seconds.Â
So I figure if it were not for com.apple.securityd, shutdown would be instantaneous, just as Snow Leopard was.Â

I know this isn't the first post on this. Just thought i would make another post on this to press the issue with apple.I Got a nice shiny new 12 core about a month ago. In the process of beefing it up with what i need on it. about a week ago, one day, it decided not to connect to the Internet. I looked here on the community and see it is occurring with lion. Came back to it the next day and it worked smooth like butter. No problems connecting and it wasn't slow at all.
As of now it has been 2 brutal days of either no connection OR a connection soo slow it reminds me of dial up. Maybee even slower. The only thing different on my computer right before it happened was i installed another HD and 16GB of owc ram ( took out the original ram).

Before the machine was superfast, now it still is but the animations go slower. (for example: switching to fullscreen apps goes "laggy". When I empty the bin. The prompt window pops up laggy etc...) I had a macbook pro before also with Mac OS X Lion, i updated the ram too and became also laggy. After a while it disappeared. For no particular reason.

I recently ran monolingual and installed Sophos antivirus. I think the problem started after Sophos free antivirus for Mac. But now the computer frequently displays the spinning wheel but Activity Monitor shows no CPU activity. While this happens I can not do much with the computer.

I came from OS Snow Leopard on a fairly basic Macbook Pro 13 inch model, and upgraded to Lion. I use Finder a lot, and something I noticed immediately was how SLOW finder is now in OS Lion. Does anyone else seem to be having this problem? When I use the space-bar to preview something it can take up to 10 seconds for me to load a preview, where it used to be instantaenous in Snow Leopard. I also have problems moving around in finder, like going from Downloads to Desktop, there's a 5 second delay minimum.
