MBP downgrade to SL from Lion without backup drive

Hi there,
I bought my 15 inch MBP only about 4 weeks ago with SL installed already on it.
Yes, I have made the mistake of upgrading to Lion and I have not made any backups at any point.
I am experiencing monitor crashes when I resume from sleep.
My MBP also did not come with a SL installation disc.
My question is simple - if I buy a copy of SL from the Apple store and install it - will it work?
Thank you.

As I answered in the other copy of this question you posted:
Purchase replacement discs from Apple: Apple Store Customer Service at 1-800-676-2775 or visit online Help for more information. To contact product and tech support visit online support site.
Purchase a copy of Snow Leopard which may work provided your computer doesn't require a special build of Snow Leopard.
However, I suspect reinstalling Lion may well fix your problem:
Reinstalling Lion Without the Installer
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alterhatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

Can i revert to snow leopard from lion without a time machine backup?

can I revert to snow leopard from lion without a time machine backup?

You can with a Snow Leopard DVD, but if you don't have that or a Time Machine backup there's no way.

How do I delete a folder that I moved to Trash from my external backup drive when a virus was detected? Trash will not delete the folder.

I have tried unsuccessfully to remove a folder from Trash. My anti-virus program (Sophos) detected a virus which had to be manually removed. I tried (unsuccessfully) to find and remove the infected file. I moved the Folder from my external backup drive and placed it in Trash. Now I cannot get Trash to delete the folder. It asks me if I wish to delete "unlocked" or "all" items. Either selection does not delete the folder. I went to change the permissions to "read & write" and unlocked the folder, but it is still there. I tried to "move" the folder from Trash back to the external harddrive but it seems I can only "copy" it and not "move" it. I am afraid that by copying it, I will not have the folder in two locations (Trash & External HD).
Would appreciate any suggestions and guidance on this. I hope that I have explained the problem clearly!
Thank you!

Before deleting it we should know more about this folder and its contents.
If it is invected and is using other apps, or other apps are still using it, then it cannot be deleted in the normal manner.
You might contact Sophos and ask them about it.
If you are using TM or have a backup of your system before the infection occurred, then you can delete the item(s) in Trash, but there is the possiblity of system corruption and the need for a reinstall, if any of these files are necessary for the OS to work properly, even though they are infected.
Sophos may not have been able to remove the infection from inside a file which is why they suggested manual removal.
You might consider downloading and running ClamXav first and see if it can't do better than Sophos.
All that being said, you can always remove the contents of the Trash using the terminal. Usually as administrator, or in some cases as root (su). Unless you are very familiar with the terminal I do not suggest doing this without some study.

Install Lightroom 6 from CD without CD-Drive

Can I install Lightroom 6 from CD without CD-Drive via an other PC?

You could copy the disk contents to a thumb drive or external hard drive and run the installation from there.
Alternatively install the free version of Creative Cloud; then click the Try button for Lightroom CC 2015. Serialize with the number from your disk packaging to convert to LR6.

How can I go back to Snow Leopard from lion without loosing files, etc.?

I recently downloaded Mac OS X Lion, but I can't stand it. I've heard you can't get a refund from the app store but I'm not sure how that works and I'd realy like my money back. Also, if I do downgrade, I'm not sure how to back up my files. I have music, documents, and pictures I don't want to lose. I don't have time machine. I have a usb but I'm not sure if it is capable of holding music from itunes? Other than that I'm not sure how else to back up things. I realize I have a lot of questions and I'm not exactly well informed with this stuff so any help would be greatly appreciated (:

See Kappy's going back to SL from Lion guide and Bombich's Get Ready for Lion tutorial.

How do i downgrade to Maverick from Yosemite without using Time Machine

Hi , there , so i have a mbp 15' mid 2010 , and i thought hey why no update to the latest software, cause why not.
biggest mistake. my start up and restart has been real slow and i think i could live with it until safari starts to crash real often.
so yeah , here i am asking for help because my last backup from maverick is dated way back to July and i do not want to lose all my stuff ( not really sure how time machine works )
thanks in advances guys !

You will have to make a backup of your current content as reverting back means erasing the hard drive.
Rename the older backup as you do not want to over write it...then restart on the recovery HD partition by holding the Command and R keys. Choose Disk Utility, then the internal drive where Yosemite is installed, and Erase.
Then choose Restore and drag the old backup to the Source box and the drive you just erased, Macintosh HD, to the Destination box.
After that finishes, could take a fair amount of time, you will have to start picking specific material from your latest backup to restore...DO NOT restore the whole backup as that will take you right back to Yosemite.

How can I restore the recovery partition of Lion without erasing drive?

Hello there,
I have a mid-2011 MBP equipped with Snow Leopard, but at one point I needed to access the AHT, which doesn't boot from the second DVD, released months before. It turns out this Mac requires AHT to run from Lion's Recovery HD partition. Since this Mac doesn't contain any Lion software, is there a way I could install the content of Recovery HD without reinstalling Lion itself so I can have the AHT ready if I need to? Of course I don't want to erase nor get rid of Snow Leopard. Drive is not original.

Apple Hardware test is only available two methods on Intel Macs
Pre-July 20, 2011 Macs through the prebundled installer discs you can order for around $20 from AppleCare if you lost the disc. The 'D' key boot then boots off the disc that contains the hardware test
Post-July 19, 2011 Macs through the 'D' key boot (no CD/DVD necessary, and no installed software necessary)
Both methods are described here: http://support.apple.com/kb/ht1509
Dates given are based when the vintage of the Mac was sold through Apple authorized retail stores, and not when you bought an operating system or purchased used or refurbished.

Delete large file from Time Machine backup drive?

I recently selected to exclude my Aperture.library file from Time Machine, but only after it had done about 8 backups already... the file doesn't exist in the latest folder on my TM hard drive but it is there in previous ones.
how can i delete this file from my TM backups and regain 40gb? (it won't let you delete it in finder)

Ewen,
Let me make my self more clear.
Because of the Apple KB article regarding Aperture and Time Macine, that's exactly why i chose to EXCLUDE my aperture.library file from time machine.
Please don't read any negative tone in this, i'm just trying to explain myself.
But hind sight is 20/20, so i was looking for a way to delete the old previous version of the aperture.library that was sitting on my backup time machine drive (useless taking up space)
I apologize for not searching out that KB article, but i didn't think i'd have to do that. I assumed Apple would know how to have Aperture play nice with Time Machine....
Any way all is good. we're all educated now

How to transfer all data from an external backup drive to a new external drive?

How should i do, to go back to leopard from lion, without loosing my applications?

Ok, being an update freak as well installed Lion and regretted it as ****!!! Now down to the thing.. My problem is not that much of data but applications. Since all of my work/projects are stored in ext HDs, i was wondering if theres a way somehow to downgrade or erase (?) to Leopard (of course) without loosing my applications.. Is it possible to copy the app folder somewhere, erase Lion , install Leo and paste app folder when system is installed? Will still work?
Thnx in advance

One of two ways:
1. Restore the backup you made before installing Lion.
2. Export your application data to formats supported by Leopard. You'll need to tell us which data you have in which versions of which applications. Clone your system twice. Erase and install Leopard with nothing but Apple keyboard/mouse and display connected, and selectively restore data that is compatible into the applications you need.
An alternative, find a Lion compatible application to your data that you used in Leopard:

Is there any way to downgrade to 3 from 4 without the shsh blob

I recently updated my itouch 2g to os4 and then found out that one of the apps I had won't run on 4. I didn't save the shsh prior to the upgrade so I'm guessing there is no way to downgrade. Does anyone know if it is possible without the shsh blob?
thanks

Alternatively, check for updates to the App. If not, contact the App's developer to ask if and when there will be an update for it that will cause it to work with iOS4.
It's odd though, that an App should stop working after an update to the Touch's firmware. You'd think the App's developer would sort that out very quickly.

Downgrading to SL from Lion

I will tell you anybody who asks don't upgrade to lion from sl. I did this and now cannot connect at my college network anylonger. Apple can't help and IT dept at school can't help. It works everywhere else and worked fine there until I upgraded. Apple told me to reinstall SL, which I have tried but now my computer tells me it can't open my disc because a newer version of mac os x is installed. Can anybody tell me how to erase my computer and reinstall the SL op system.

You need to copy your user files off to a external storage drive first and disconnect.
To boot off the 10.6 disk you need to hold the c key down
Follow the
Restoring OS X - 10.6 "fresh install method"
https://discussions.apple.com/message/16276201#16276201
Some tips:
Do NOT restore from TimeMachine that's been connected to Lion, erase and reset it to Snow Leopard when your back on it.
For your iPhoto, you may need to right click on the iPhoto Library and "show package contents" to copy out the Originals, then import them into the new 10.6 fresh installed iPhoto.
For iTunes you may need to copy only your music out of the iTunes folder and reimporting into 10.6 iTunes, this means losing playlists.
If you assign "groupings" to your music files on iTunes Lion, it's a tag that sticks to the music files themselves, when you transfer back just the music into iTunes on 10.6 then all you have to do is create Smart Playlists based upon the grouping tag to restore your playlists.
If resintalling Snow Leopard is beyond your ability, you can find a Mac person on campus that can assist you.
Some college networks use software that hasn't been updated to work with 10.7, so they don't know what you are when you try to connect, thus they cut you off.
Your likely right you have to return to Snow Leopard until the college gets updated software, whenever that occurs.

How to downgrade to SL from Lion?

I have a 21.5 inch iMac that I want to re-install so I can sell it in a clean state. Unfortunately, I lost my original install discs so I called Apple Care (who don't care AT ALL) and they told me that they no longer are able to ship out replacement discs and my only option is to purchase a SL disc on the online store. I ordered a SL install DVD and once it arrived found that my iMac won't boot from this disc.
So, I called Apple tech support again and was now told that I can't do what they had suggested I do as described above because apparetnly OS X Lion makes changes to the iMac.
I am left *really* frustrated with Apple's arrogance and unwillingness to help. The agent's only response was to point me to the legal agreement for OS X Lion and he also stated "it's in there somewhere" but couldn't be more specific.
Has anyone been successful in obtaining replacement discs? if so, how?

Ok I get three 21.5" iMac's

How to erase and install Snow Leopard 10.6
2: Mid 2010 - Came with 10.6.3 - 10.6.4 this computer will NOT boot off the 10.6.3 retail disk (despite what some Apple employees say, no hardware drivers for your machine)
3: Mid 2011 - Came with 10.6.6 - 10.6.7 this computer will NOT boot off the 10.6.3 retail disk
So, I called Apple tech support again and was now told that I can't do what they had suggested I do as described above because apparently OS X Lion makes changes to the iMac.
Only to the hard drive which can be entirely erased and 10.6.x placed back on as the machine came with it.
The firmware or anything else is not changed to deny booting off the 10.6 disk, provided it's the right one.
The agent's only response was to point me to the legal agreement for OS X Lion and he also stated "it's in there somewhere" but couldn't be more specific.
The legal agreement with Mac App Store software (which 10.7 is upgraded from 10.6.8 with) is your supposed to erase it when changing ownership.
Tell them you either need a notarized waiver or the 10.6.x machine specific disks or expect them to hear from your attorney.
Make sure you get their names or employee ID information, that usally gets their attention and a bump up to a smarter animal.
You can't open the iMac and replace the drive neither, like one can in a MacPro or MacBook Pro, so you need the correct disks.
You can choose to erase and install Lion, but it will be using your AppleID. Lion isn't copy protected, but the MAS software is so you can't restore that.
To boot off the 10.7+ Recovery HD partition, hold command r (or option) and reboot. Use Disk Utility to erase the OS X or second partition with the Security Option Zero to remove bad sectors. The "Zero" option is one step below the maximum 7x setting.
Use the installer with a good reliable fast Internet connection to reinstall Lion.
About the Recovery HD 10.7+ How to secure delete data from the machine
This wipe and install method is usually used as a last resort when Disk Utility is unable to see or repair the drive. Or if ownership of the machine is being passed to another.
When OS X is reinstalled using this method, upon reboot the Welcome to Mac video shows and will repeat unless a new account is created.
The problem with leaving 10.7 on the machine is if the next owner is a criminal online and the cops go to Apple for information, your AppleID is the last OS X version downloaded to the machine.
