I'm running on Mac OS X (ver 10.7.2) on my Macbook Pro 15. I did an update earlier this morning and after that everything I run fails or runs really slow. Some of my application also don't work properly anymore. My guess is when I did the software update and it rebooted, It failed to complete the installation and just rebooted. So I think the update wasn't installed properly.

Here are some problems that it caused.

  1. Whenever I plug a thumb drive or external HDD it's not being mounted. But I can see the drive in Disk Utility. The USB port i think is working because I use it for my wireless mouse. - my guess is the drive for external drives got corrupted.

  2. When I try calling someone on Skype it logs me out.

  3. There are some lags with the animation. e.g. when i run the Launchpad it has a laggy and harsh animation. It's feels like the animation only has 3 frames so it isn't that smooth.

  4. It's really slow!

I just bought this laptop last week and It didn't come with a Mac OS X CD. Is this normal not having a CD?

Some solution I'm planning to do:

  1. Reformat/Reset my Mac OS X -problem, I don't have the CD

  2. Repair the driver -problem, I don't know if it's really the driver fault or which driver I should install

Please advice what should I do. The nearest apple store is also far from where I live - so this is my last option to send it back to the store.

Apple Macs (desktop and laptops) released since the launch of OS X 10.7 Lion do not come with Install DVD or Software Restore DVD. Apple charges for OS X 10.7 Lion sold in a USB thumb drive. – Global nomad Nov 29 '11 at 14:49
@Global nomad. Good to know that. thanks! – Pennf0lio Nov 29 '11 at 16:10

Try a SMC Reset:

You can also re-download the update and try again (=combo update):

will be trying the combo update. thanks! – Pennf0lio Nov 29 '11 at 16:49
I've tried installing the combo update but It didn't fix it. So I'll be trying to re-install lion instead. thanks! – Pennf0lio Nov 30 '11 at 7:01
Oh, that sucks! Did you create a bootable install USB with lion? I've created one with the installer .dmg. That's much quicker since Lion does not have to be downloaded first.… – gentmatt Nov 30 '11 at 7:08
Instructions to re-download Lion:… – gentmatt Nov 30 '11 at 7:11
actually i've gone to a LOT of stuff just to re-install the lion again. I now have the lion but wasn't successful in transferring in a thumb drive and in my DVD. my thumb drive is only 4 GB so i think it haven't accomodate the file properly, I've also burned it on a DVD but since it has some problem in mounting. the DVD can't be run or also corrupted. lolz – Pennf0lio Nov 30 '11 at 20:40

After re-installing lion the issues still remained. The drives are not being mounted, the animation are still laggy and sluggish, and speaker are disabled even i can hear the chimes from the start up.

After that I brought my MBP to the nearest Apple re-seller that I can find. (btw, The technician is very accommodating to hep me) We tried a lot of stuff and different approach to fix and got lucky in resetting the PRAM (Ctlr + Option + P + R).

That's what I said in the last comment! =) I also had to do this. – gentmatt Dec 2 '11 at 6:22
Hi Matt, Are you referring to SMC? I tried the SMC reset but didn't resolve the issue. – Pennf0lio Dec 2 '11 at 10:53
No, I mean't the PRAM reset. You need to click on "show 2 more comments" on the first answer. – gentmatt Dec 2 '11 at 13:18
Darn! I missed that.. I wished i've seen that earlier.. thanks a lot! – Pennf0lio Dec 5 '11 at 6:44
