How to reinstall OS X Lion on macbook pro late 2011 ?
Hello all !
I'm new here and pretty new to Macbook Pro had for just over a month now.
I baught it expecting it to be fast and good though I seem to be getting hard time doing simple stuff and having connection problems plus it slows down on me.
My family members have been downloading all kind of stuff and my MBP is pretty slow since then and wierd stuff is occuring.
I would like to reinstall Lion OS X to make as new agian since I think this solution only might help me here.
Though when I baught this MBP I didn't recieve any CD's with it as in basic OS X installations.
My question how am I supposed to reinstall my OS X and my MBP ? Please help me I am so fustrated because of this.
Relevant information about my MBP:
Macbook Pro 8,1 - 13" Late 2011
Version 10.7.4
2.8 GHz Intel Core i7
Main issues:
Wi-Fi keep dropping and Safari is acting way to slow.
Invisible files appearing and are Visible on desktop such as (.DS_Store & .localized)
Many other gliches that prevent me copying simple stuff and closing Safari or tabs in Safari.
Thanks to all in advance.
What do you suggest then ?
I suggest troubleshooting the problem instead of just guessing what has to be done. Since you're within 90 days of purchase, you're eligible for phone support from AppleCare.
Stop the secure erase. Quit Disk Utility and either restore from a Time Machine backup or run the Installer. You don't mention whether you have a backup. I hope you do, because otherwise your data is lost beyond any hope of recovery.

I have a late 2011 MacBook Pro 13" and bought a brand new iMac 27" last week.
I tried to transfer data (musdic & photos) via Thunderbolt, but i did not run, my system always
tries to transfer data via WLAN, but that would last more than 80 hours.
I tried to get some help from the Apple Support, but unfortunately they couldn't help me.
A promised call-back from the next higher support-level has not been done.
Does anybody know what the problem might be.
The Thunderbolt-cable is brand new.Instead of using Migration Assistant, the best way is to use the Target Disk Mode, so you will save headaches (Migration Assistant creates a new user with the transferred data).
To do this, just connect both Macs with the Thunderbolt cable, and then, start the MacBook Pro holding the T key, so a Thunderbolt or FireWire icon should appear on the display. After that, go to the iMac, open Finder, and the hard drive of the MacBook Pro will appear on the Finder sidebar as an external drive, under "Devices". Just access to it, go to the folders with your iTunes and iPhoto libraries, and copy them to the iMac -

MacBook pro late 2011 i7 8GB 750GB MAC OSX Lion freezes on wake up
Hi,
My MacBook pro late 2011 i7 8GB 750GB MAC OSX Lion (up to date) 1 week old freezes on wake up.
Plugged on power or not, same issues.
No apps running.
When it goes to sleep itself i wake it up it freezes for few seconds
When i put it to sleep mode same issue.
With the lid same issue...
I already try setting up the sleep mode from 3 to 0 with terminal command it didn't work.
Can it be an hardware issue ?
Any ideas ?Dear TheSmokeMonster, Dear all MacBook pro 13'' late 2011 users,
Here is the update.
As TheSmokeMonster mentionned (above) they asked me to reinstall MAC OSX Lion by shutting down the computer and holding cmd + R while switching it off. Then you choose the language and you are good to go for a looooonngg 4GB download (it took me 8hours yeah chinese ADSL :-/ )
Lion reinstalled itself automatically and restarted. - it did not solve the issue.
I called Apple Care again and we try to run the hardware diagnostic by restarting the computer and holding D. FYI do not try it as this command does not work on the new version of macbook pro.
Here is the intersting part! As the Apple Care already did everything they could to help me. We booked an appointment the my local Apple Store in Shanghai (a real one )
The Genius remake again the SMC and PRAM reset - same issues and he also tried to boot Lion from his own external hard drive - Same issues. So we started to think that it was a Hardware problem.
We tried another MBP 13'' late 2011 (last hardware update) in the shop to see if it works properly and it DOESN'T!
Yeah you heard me. I have been trying more than 10 MBP 13'' (2.4Ghz 4GB and 2.8Ghz 4GB) put them asleep and they all freeze on wake up!! it also does it on Mac book air 13'' it seems to be a global issue on all the new 13'' machines. A compatibility problem between Lion and the new hardware architecture of the 13'' ? just my guess.
Anyway FYI this issue doesn't occur on MBP 15 and 17"
I was just amazed by this global problem so was the genuis. We could not find any solutions cause even a replacement one will have the same problem. They told me i could change for a 15" but i had to go back to the Apple shop where i bought it which is 2000Kms away not really convenient So i file the cas and i took my MBP 13'' back with me.
They will contact me later for further explanation.

How do i use my imac 21.5" 2011 as a display for my macbook pro late 2011, through thunderbolt cable ? I have tried and it doesnt seem to work, neither does target disk mode.
Could it be a borked cable ? I just bought it new from the store today, i have updated both imac and macbook pro to latest thunderbolt firmware and updates. Both 10.7.3.
MacBook Pro:
Vendor Name: Apple, Inc.
Device Name: MacBook Pro
UID: 0x0001000A17016E60
Firmware Version: 22,1
Port:
Status: No devices connected
Link Status: 7
Port Micro Firmware Version: FFFF.FF.FFYou are correct, here is what Apple Says:
http://support.apple.com/kb/TS3775
I was able to find these instructions, however they referr to 2009-2011 27" iMacs. I think it's the same, if it's not then contact Apple directly for instructions. If either of the machines is less than 90 days old or covered by AppleCare then call AppleCare tomorrow for help, they should be able to easily answer this for you. You will find the number in your manual or you can use the AppleCare Contact Info link.
Your iMac should automatically recognize the presence of a digital video signal at the Mini DisplayPort and enter Target Display Mode.
If your iMac does not automatically enter Target Display Mode, press command + F2 to manually enter Target Display Mode. -
How do I install the recover portion of OS X 10.10.1 on my MacBook Pro late 2011? It is missing!
When I boot up my MacBook Pro late 2011 while pressing the option key it should show the recovery icon which it doesn't.
How do I install this portion of Yosemite?This was changed with Yosemite. The recovery is hidden when booting with option. Hold command and R when booting to get into recovery (without option). If you see the globe, then it is actually going to Internet recovery, which means you do not have a local recovery.

Does airplay mirroring work on MacBook Pro late 2011 ( Mac OS X Lion 10.7.5)?
Hi guys,
I would like to use airplay mirroring on apple tv (3rd generation) with my macbook pro late 2011, unfortunately the airplay option does not appear in the display preferences (see screenshot below). Did someone have this problem before? Please advise!
Thank you!
TialWelcome to the Apple Support Communities
See > http://support.apple.com/kb/HT5404 Your computer is compatible with AirPlay Mirroring, but you have to upgrade to OS X Mountain Lion to get AirPlay Mirroring.
Make a Time Machine backup and/or a clone with Carbon Copy Cloner, open App Store and purchase Mountain Lion. When the download finishes, the installer will appear, so follow the steps to upgrade. To turn on AirPlay Mirroring, select the AirPlay icon in the menu bar or open System Preferences > Displays -

Will OS Mountain Lion slow down my MacBook Pro (Late 2011) running 10.7.5?
I have a Macbook Pro (Late 2011) that is currently running OS Lion 10.7.5. I was just wondering if updating to OS Mountain Lion would slow it down in terms of performance, or if it will have any other bugs on my MacBook?
PS. When updating to a different OS, do I have to back up my files to like a hard drive or something?When updating to a different OS, do I have to back up my files to like a hard drive or something?
A back up is a precaution that you should always have, not just when installing an update to the OS. Its purpose is no different from the seat belt you wear when you drive. Use it all the time, and hope it will never be really necessary. -
Macbook pro late 2011 is on Mac OS X v10.7 Lion and it is using lot of RAM
Macbook pro late 2011 is on Mac OS X v10.7 Lion and it is using lot of RAM...when I turn on after 2minutes it freezes and do not repond and system prefrences also not working...plz help me....I don,t have mac os disc
I have tried safe mode boot, NVRAM and PRAM reset but no luck...First, try a Safe Mode boot.
Startup your Mac in Safe Mode
A Safe Mode boot takes a longer than a normal boot so be patient.
Once you are in Safe Mode, click Restart from your Apple () menu.
If that didn't help, reintall OS X..
Restart your Mac while holding down the Command + R keys so you can access the built-in utilities in OS X Recovery

Both Internal hard drives fail on Macbook Pro late-2011
Both internal hard drives (SSD and HDD) failed on Macbook Pro late-2011.
Setup: MBP closed with Thunderbolt display attached.
Problem on HDD-A
I called Apple Support to log an issue with my MBP2011. The system is made up of 2 drives - SSD (128GB) and HDD with 2 partitions HDD-A and HDD-B(original 750GB).
HDD-A has LionOSX 10.7 and HDD-B is storage. SSD has LionOSX on it as well. I normally boot HDD-A.
I was working on HDD-A and the Kernel Panic screen appeared prompting me to shutdown the machine and start it up again.
I tried to reboot HDD-A and the grey progress bar appeared for a long time. I then forced shutdown and rebooted into SSD.
I was able to boot from SSD and then I opened Disk Utility to check the drives. I verified the disk for HDD-A and there was an error. I then tried to repair disk and it couldn't repair it. A dialogue said the disk could not be repaired and that data should be backed up.
HDD-A was not visible in Finder but HDD-B was accessible.
I verified HDD-B and it was "ok".
I shutdown, booted from SSD, disk utility HDD-A and the same message occurred.
I called Apple Support and they advised that I boot from my external HDD which was a clone of HDD-A.
Solution
I was successfully able to boot from the Clone HDD-A.
HDD-A was able to be accessed and I could retrieve the files from HDD-A.
I copied over the latest files from HDD-A to an external drive.
Same Problem on SSD
Boot from SSD, i started working for about 3 hours, with the lid closed, and attached to the ACD.
Kernel Panic screen happened again on the SSD.
Couldn't boot boot from either SSD or HDD-A.
I booted from Cloned HDD-A, Disk Utility verify and repair returned errors on SSD. The same issue had occurred on the second drive.
Disk Recovery from a boot recovery USB thumb, Disk Utility, erased SSD, verify was ok.
Tried to install then there was an install error saying that SSD was damaged (large triangle warning icon). Tried 3 times, failed.
Boot from Recovery Drive HDD-A, downloaded LionOSX.
Next steps
Format HDD-A and HDD-B into 2 partitions
Install LionOSX on HDD A.
Note:
I did not do any software updates for about a week before 14.04.2012 and suspect it might be due to the virus.
I normally work with the lid closed and attached to the ACD, I also suspect that overheating caused both drives to fail. However, I have been using this system with the lid closed for atleast a week. One Kernel Panic screen occured.Depending on what you are doing on the computer, how hard you are working the computer, it should not overheat. And if it does it should shut down or get very slow because when it starts to overheat the CPU will be throttled back to a lower Ghz speed and or just shut down so it doesn't cause damage to the CPU. The Kernel Panics are a sign that something else is going on. This could be software or hardware.
If after wiping the drives and reinstall Lion on the SSD if the system is running OK then the drives are fine, IE they are not bad. There is something else corrupting them. Again this could be hardware or software, but I doubt it is heat. And using the MBP ion clamshell mode should not cause overheating or excessive heating of either of the drives.
Have you installed iStat Pro or Menu and kept and eye on the temps? If not install iStat Pro and keep and eye on the temps. I bet they do not get above the 150°- 180°F mark which although hot is not overheating.
Be very careful when calling Apple. Removing the DVD drive and installing a hard drive in that bay could void your warranty. The DVD is not a User Removable part and Apple frowns on doing that. So if you call them do not mention that you have replaced the DVD drive with another HDD.
Honestly I suspect you have a hardware problem. But the only way to know that is to install just Lion and your basic programs and run the system. Leave out any AV type software, if you are running some. If you don't get any kernel panics thenn install some of your other software, one programm at a time. If with just the OS and basic software you get a kernel panic then it is hardware related and needs to be checked out by Apple. If you do that re-install the DVD and the original HDD with just the OS on it before you take it in. -
Hi everyone,
I have a big problem with my MacBook Pro late 2011, suddenly while working without connecting the charger and it is 100% charged the screen would go black and I would need to hold the power button to shut it down and then power it up again, The second issue is the superdrive whenever I use a disc it spins it for 3 times before ejecting it to me, tried resetting PRAM and tried re-installing mac os x mavericks, but no solution so far and about the superdrive I bought a cleaner disc and tried to insert it, the superdrive would spin it 3 times and ejects it after that. Saw the disk permission solution and tried it once and I think there is a problem with that because this is the second time I try it and it was saying that there were problems.
Sorry for being long.
