Q: El Capitan Ruined My Macbook Pro

On another working Mac, you can download El Capitan from App Store. Then create a USB installer, using Diskmaker X. Boot your Macbook, holding down the ALT-key on your keyboard. Now choose the USB stick as youre boot-devise. When the menu pops up, start Disk Utility, and format your harddrive in the macbook pro. Quit Disk Utility, and install El Capitan, on the newly formatted harddrive. Your Macbook should now work.

MAKE SURE TO BACKUP YOURE DATA BEFORE FORMATTING YOUR HARDDRIVE

OS X: About OS X Recovery - Apple Support

make sure you are following the procedure for your model mac.

You may also try using the install DVD to perform this if you have your data backed up.

You could to the USB boot Yosemite with Windows, I have not tried El Cap.

FileVault gave me boot times that were rivaled by my Atari 410 tape cassette drive and it took me HOURS to unencrypt a 500GB SATA drive so I'm not a fan of FV.

Mine and many other computers won't even run when restored back to an older OS now.

I'm seeking others in filing a class action lawsuit against Apple for their wrongdoing in this OS release. I feel there is enough evidence to support that they planned on rendering older laptops useless with the upgrade. Mine and many other computers won't even run when restored back to an older OS now.

This is nonsense.  Older laptops, whether Macs or PCs, are eventually rendered obsolete by continued upgrades in operating systems, hardware, and security features.  That's how it works.  If you installed El Capitan on a computer that was too old to support it, that's your fault, not Apple's.  They list, quite clearly, the computers that can take an upgrade, and the kinds of specifications on your system that need to be there.  If you don't bother reading that information, again, that's your fault, not Apple's.  95% of the people who post questions/complaints here about something that has gone wrong since upgrading to El Capitan have their problems solved by removing out-of-date, bloated, third party crapware from their hard drives. 

This is the document you agreed to when you updated. If you did not read it in it's entirety or you misinterpreted any part of it that does not dismiss it's content.

At least the fanboys have arrived to the rescue of the mighty corporation.
The upgrade is not too old to support my computer, it is well within the boundaries of upgradable machines, not even towards the bottom-end as far as age goes. The computer won't run without random shut downs; even when 1 of several other hard drives with older operating systems on it is installed. I did not go head first and upgrade without having many backups. I maintain my machines. This is not a hard drive issue, it is not a battery or power supply issue (both of which are new) - I have had several techs look at it for an outside opinion other than my own, all of which agree that the OS altered the firmware of my GPU or logic board, which has now rendered it a paperweight.

not fanboys but I'm an IT professional with many years of both Windows and Mac support in corporations. If your "several techs" think the logic board did fail take it to an Apple Store for a diagnostic and they can tell you for sure, they can either estimate a cost or it may be under warranty depending on circumstances, or it could be another cause entirely. Otherwise your soapboxing is out of line to everyone who's taken time to provide you with free advice and expertise.

I'm not a "fanboy."  I'm not even a boy.  I'm an Apple user just like everyone else here, no more, no less.  I don't need to rescue Apple, for they don't even know I exist.  As for why your computer suddenly became unusable, either there was something else going on before you upgraded to El Capitan and didn't know about it or you're one of the extreme minority of people who have downloaded it and experienced legitimate problems.  Either way, there's nothing wrong with El Capitan.  If El Capitan was faulty, if there was something truly wrong with it, lots more people would be experiencing problems, and they're not.

I also find it highly unlikely that El Capitan altered the firmware of your computer.  That doesn't sound like something an operating system, no matter from which company, is even capable of doing. 

After i upgraded to El Capitain my computer suffered a failure, and all i got was the gray screen.

Apple helped me determine that my early 2011 -17" MBP was eligible to have a new "free Logic bored installed" by Apple. Deadline to have this done is End of Feb. 2016. Check that out.

since your an "IT professional" you should be fully aware that OS upgrades/alterations can at times make systems inoperable. I brought the computer to the Geniuses at Apple and they're stumped, they recommend to send it in for a wieldy repair charge. In response to the free advice I've gleaned here, who needs enemies with support like you.
