jswin......you've summarized my dissatisfaction very well. Additionally, I can no longer mount my external NTFS hard drive (not sure if it has to do with this drive being connected via USB when I downloaded/installed Lion).
Basically, every application is running much much slower or just crashing (e.g. Firefox, Word, Finder, etc.)
Sadly, I'm seriously considering using Time Machine to revert back to my Snow Leopard system from early Thursday morning.
Ok guys I had the exact same problem but I think I found a solution. I just did it about 30 minutes ago and since then my MBP is running just like it used to with snow leapord. No gaurantees that i fixed the problem but this is what i did. I went to Applications>Utilities>Disk Utility. I then ran a verify disk scan and found that there were many problems with me Macintosh HD drive. It said I needed an install disk of lion to fix. Since there is no disk I thought I would experiment and this is what I did.
1) shut down my computer and then started it back up while holding down the alt key. (this should bring up two disk options to run your computer)
2) I chose the second option (I believe it is called something like "recovery disk" but dont quote me on that. you want to select the one that is NOT Macintosh HD)
3) It loaded and then gave me four choises of what to do. I clicked disk utility.
4) From there I ran the verify disk scan again then clicked repair disk.
5) I then ran the verify disk perrmissions scan and then repaired those as well.
6) then I restarted my computer and spotlight indexed the computer (i let it do its thing without running any programs) once it was done my computer worked so much faster and for the first time I can say, I AM GLAD I HAVE LION! I hope this is a permenant fix. Please let me know if you try this and how it works for you
I couldn't agree with you more! After installing Lion, it's like I have gone back in time to when I saw a sluggish PC with Windows! Ever single application I use is slower - the graphics are so jerky is horrible, saving files is OpenOffice is slow, surfing the web with Chrome you name it!
Could this be due to severe disk fragmentation after two OS upgrades (Snow Leopard & Lion)? To me this is doubtful as I have only used 25% of the available disk space but perhaps it is. "Disk Utility" gives no information about disk fragmentation though.
So what is it? I have plenty of memory and disk space so there's only one thing left: CPU. Did Apple forget to turn off debug mode? Is it the new security enhancements which slow down every single OS function call?
There's definitely something rotten in the state of Denmark... And I really don't have the time and energy to find out what!
I seem to have fixed the problem on my MBP i7. I shut down the computer and booted it while holding down the OPTION key. Then, select Recovery HD and click on the arrow. Select Disk Utility. When it's openend, select your Mac HD. I first clicked Repair Disk. As it went through this, it reported that my HD was fine. I then went to Repair Disk Permissions. It found a fair number of problems during this process and repaired them. After it finished, I restarted the computer and it seems much better now. I hope this process works for others.
Thank you so much! This seemed to have worked on my Early 2009 White Macbook. Hopefully Apple will have an update soon to fix the slowness in other areas. Did you notice your Preview even being slow? Mine was terribly slow before I did was you said, xraydoug. I was constantly getting the spinny wheel of death when I would switch through the pages too fast in Full Screen in Preview. Fortunately, doing this helped a lot! Thanks again.
Thanks for the responses, everyone. I found disk permissions errors as well, but I will never know if that was the problem since I had already transferred all of my data off my machine to do a clean install, so I took that route anyway. The clean install fixed EVERYTHING! My machine is smoother than ever now. If none of the above works, install from scratch using a DVD with Lion on it (you can find instructions on how to burn a Lion DVD virtually anywhere now) and your problems should disappear. Enjoy Lion
Hi xraydoug - Thanks for the info. Did exactly as you said but to no avail. Still very slow and getting the rainbow wheel nearly every time I browse. Prior to download everything was excellent. Looked at most other users who have now found their mac to be much slower when Lion downloaded. Will try and wait to see if apple come up with some solution. Thanks again
I experienced loads of issues with my os x Lion install - my 2.53Ghx i5 was just crawling. I tried repairing disk permissions with little effect.
Then i disabled quicksilver. I knew it wasn't compatible but since it has been running on my macs for 5 years I was reluctant to get rid for some reason.
The SECOND that I quit it from the menu bar my computer was instantly more responsive.
A complete guess would suggest that since it indexes the machine, and it's not set up to run under os x Lion yet, it was getting stuck and being a memory hog?
Perhaps you haven't had quicksilver installed, but just try and disable all background running apps before you take the drastic step of reinstalling.
Thanks for all the information here, I tried everything suggested still same problem. My Lion is extremely slow. When I restart the system, for the first 5 mines it works fast then it starts dragging and eventually it becomes so slow that I have to retart th esystem again. I checked on eh Activity Monitor to see what coud cause this and I can see abot 50% of the CPU is being used by DaemonManager. I wonder if this is what the cause is.
Please Apple, find a solution for us!!
After having wrestled with this for quite a while, repeating what I described above often, as the problem kept returning, I finally did a clean install of Lion. It has worked perfectly since. I think there is something funky in the upgrade installation path. I highly recommend installing Lion to a clean drive.
