El capitan freeze during install

Denbee, or anyone that has been successful, I'm a bit of a novice here. Can someone tell me exactly how to login to get to step #2 from the safe mode screen? There are options to Restore from Time Machine, Reinstall OS X Get Help Online and Disc Utility.

When you start your mac, just push the shift right after you hear the startup sound. Then your Mac OS will start in safe mode and you'll have access to the Finder. It shouldn't give you any of those options, rather start the system as usual but annoyingly slower than before 😝

please help!!

I have a Mac mini, and I am updating from OSX Mountain Lion to OSX El Capitan. Everything went normally in the beginning. It shut down all my applications and told me it needed to restart my computer. Then I got the white screen with the Apple logo and the progress bar. It stalled at 30 minutes remaining and sometimes fluctuates back to 31. It has been this way for 24 hours. I am unable to boot in safe mode or recovery mode. Nothing happens. I have shut down and restarted several different times and it goes right back to the progress bar.

Hello Denbee that solved the problem for mee too, thank you so much!

Actually I reboot from an external disk in order to edit the .kext files and it worked well.

NOTE that I put again all the .kext back to the Extension folder once El Capitan reboot regularly the first time and then the computer started well again despite all the extensions were back in the same folder. Actually I think is not necessary to test one by one all the .kext files.

If you do not have an external bootable disk ask a friend that have it: reboot from the external disk holding the [option] key and choose the external disk as booting system. Once rebooted you will be able access and open your internal HD and perform all the mods suggested by Denbee. Then just shoot down your computer, unplug the external disk and restart: if the problem is the .kxet extensions it should boot normally (note that the first time it takes some extra time).

Thank you so much, it worked on a MacBook Retina late 2013. Had the problem with Yosemite, could not find the reason, clean reinstall, one month of problems. Now upgrade to El Capitan, same problem, without extensions finally working.

Just had to do this AGAIN with the latest update to El Capitan! Thank you again Denbee for figuring this out! Booted from the edrive partition on my hard disk, moved kext files (only two, both printers) and voila it was solved. Oh Apple!

Denbee's instructions were great! I was able to troubleshoot the install on my MBP Early 2011 going from Mountain Lion to El Capitan. As other posters mentioned I did NOT have to try one kext file at a time. I simply copied them to the unsupported folder, re-started, installation succeeded, put them all back in, restarted, and it worked flawlessly. It saved me hours of hoping the hanged beach ball cursor and progress bar would move.

I have an early 2011 MacBook Pro and it gets stuck at the very start of the install which is a bit different from most posts I've read. I've wiped the hard drive and did a clean install of Lion off a USB, that's all I had available. Download El Capitan and same issue, tiny progress on the install Apple logo screen but it just sits there for hours. I've tried safe mode, shift key after start up sound, but it just comes back to this screen. Any thoughts?

Might be having the same issue as you, and it's got me stumped. I installed El Capitan on to an SSD, but when I install the SSD, the Mac will not boot from it. It WILL boot from the SSD if I put it in a USB case. But not internal. Are you saying that Lion DID work for you?

I have Lion on a USB and I am able to boot from that. Once I start the El Capitan install and it freezes, I have to reset the PRAM then recovery mode to delete the hard drive, then the USB Lion install Goes through. Resetting the PRAM has to be done or it won't work, for me anyway. My battery is completely dead, I'm thinking this may have something to do with it but I'm not sure. I found my Mevericks and Yosemite downloads in iTunes purchase history and am now attempting a Yosemite install however that enjoys hanging out at 20 minutes remaining for hours at a time. My hope is to get Yosemite running then try to upgrade. Thankfully I have another pro and and air so I'm not stuck without one while I work on this.

a) In my opinion, you got lucky.

B) on a desktop Mac, there are capacitors in the power supply that smooth over ripples and sags and spikes in the DC power. On a notebook computer, the battery does that job. While it is common to run a notebook computer without a battery while under repair, it is NOT recommended for daily use. Power fluctuations are conducted directly to the chips, and that may cause premature failure.

I agree, not a good idea to run without a battery for long term use. I purchased this one used from a friend of my mother's and the only issue was the battery no longer worked. It had belonged to her late husband who rarely used it. She had it serviced/looked over by an Apple tech who said it just needed a battery but she wanted a Windows computer instead. I'm just waiting for the battery I ordered to arrive. My other pro had a swelled battery that cracked the track pad. Software update was completed while waiting for replacement battery (swollen battery was removed) and went through fine. I'm down to "about 11 minutes remaining" on the Yosemite install now, which I've read many posts that it has taken some up towards 15-18 hours with a working battery. Fingers are crossed it will go through! It's already further along than El Capitan ever got but I also had less patience with that install.

Apple took over its own downloading services about a year ago (they were using an outside service). Download times have been quirky. If it somehow decides your link is slow, the actual download can take days. In general, if you end up with a download estimate that is measured is days, you should cancel it and try for something more reasonable.

Once downloaded, the actual Install should be done in an hour or less. I am not sure what would make it stretch out more than that, except a Bad Drive.
