OS X El Capitan Won't Install! Why? - Krazy Ken's Tech Misadventures

[@AnonymousFreakYT]

The "funny progress bar" was a firmware update running. I'm guessing that MBP had never been updated to a new enough OS to get a firmware update; so the High Sierra install applied it during its setup - the long beeps and multiple restarts is the behavior of a firmware update. (The different looking progress bar, too.)

[@dvlnx.]

i wanted to say the same thing...

[@thmUNIX]

Also this bar means loading in safe mode (-x argument)

[@tjsimons]

Thank you for the date tip. I spent all day stuck in a boot loop and the date change fixed it! El Capitan now installed and my Mac has a new lease of life.

[@cjc363636]

"Know the 'Why.'" From an old geezer former audio tech, that' s some great advice!

[@emp3rror]

the strange thick bar is a firmware update being installed prior to the os . in many cases it solves a lot of compatibility problems

[@brokenelectronics3665]

I just started the video. Setting date and time to an earlier year is usually the answer.

[@ComputerClan]

[@pannanap]

just started this video. are there any reason behind this?

[@XeZrunner]

It's really odd to think that these are already so old - we had no problem installing these a year or two back, as the certificates were still good, but it's 2020 already - really crazy how we don't even notice that time moves quite fast in terms of how old certain software is... Windows 8.1 is also reaching EOL soon...

Not easy to troubleshoot but before you gave the solution I knew changing the clock could fix this issue. There was a similar issue with Snow Leopard when certificates expired. Apple had a fix for it.

[@Maciek2846]

Why? :(

[@johncaybould3022]

So in short, the SOLUTION is to hold down alt/option+Command+R (entering INTERNET RECOVERY MODE) directly after starting computer and letting go of keys when the search starts or when the globe thingy appears. Your mac will probably search for the latest (or first) suitable version for your mac, which is probably High OS Sierra or sometimes the version your mac came with. Simply select the MacOS version suggested and do the installation. Good luck!

[@mspeter97]

Yeah, your High Sierra installer actually did a firmware upgrade, hence that god awful beep and different progress bar. Some installers did indeed expire because the certificate used for them went out of date september 2019 if I remember correctly. The one downloaded from Apple must have a newer certificate for it to work. That whole problem is definitely caused by an expiring certificate.

[@ComputerClan]

Yeah. That makes sense! Thank you : )

[@redrakham8060]

Oh man you made my issue video!!! I tried to install it on my hackintosh on my 2 ssd but it wont install no matter what i do or change my efi folder!! Can install other os but not el capitan

[@MattsTech]

The beep noise is a firmware update being initiated.

[@StephenCornelius]

That long beep and the different progress bar during installation is a firmware patch being installed

[@JarrodCoombes]

I am going to go out on a limb here and guess the issue has to be with the certs used to sign the El Cap installer as well as the packages used during the installation. If they are expired, then the OS won't install the package and throw ups that error. This would also explain why setting the date back fixes it, as you are essentially making invalid expired certs suddenly good again. So the take away here is if you are installing an older Apple OS, just set the clock back 1 year after that OS was released and you should be good to go.

[@johnDingoFoxVelocity]

Ok I can explain everything and you are not going to like it so high Sierra comes with a firmware update with a special nasty feature from Apple called lockout mode now lockout was designed to prevent users from downgrading back to there original operating system. The first error you received was because elcap has to be connected to the internet to verify that you legally own it and that the installer is legit. This is why a patcher was needed to create install media for this version of Mac OS X The clock does have to be changed and the reason is dumb as hell. Apples new firmware with High Sierra detects date and time after a select date the firmware is told to drop supported os so you have to roll back the date and time in order to install the os to bypass the limitation

[@IanMatthewMyers]

This is not correct. The root cause was that the very had expired in the installer. Expiration date was October 24 2019 if memory serves. You can verify this yourself if you like by taking a Mac that is HS or newer, downloading a fresh copy of El Cap, and install with it w/o rolling back the date. It will work now as the copy of the installer now has the newest cert.

[@brendandoan_]

Ken, I'm glad you made a video about this. When I tried to install El Cap it does the same thing. But the machine i tried to install it on was an iMac. (9,1) Even though it is an older machine i still contacted Apple and had to call them several different times because nothing worked. But then i ended up putting Catalina on it and it worked better than it did before.

[@ComputerClan]

You're welcome. I learned a few things while putting this together, too.

[@bennaambo2716]

nope that big bar after the beep is a Firmware (EFI Firmware / SMC Firmware) update installing

[@JackWeekes]

I would have recommended installing an older version like lion, then updating it to El Capitan that way.

[@AsianFlex]

thats what worked, exept i used snow leopard

[@webslinger2011]

I've upgraded my c2d 2.4Ghz 7.1 macbook white to use an ssd(Still on Snow leopard cause I have old paid software on it) but running Maverick and El Capitan from a usb. Still runs snappy. Did a video on it as well. Setting the clock backwards works.

[@psyphi407]

[@tchang3609]

What worked for me was to go to Settings and then Date/Time and just turn off the the Auto Set function and then just turn back the clock - but in this case I back dated my iMac to around 2012 and then proceeded with the update. So far this seems to work since I've not had any error messages.

So I deleted everything to do with El Capitan and just let it sit there for a couple of months. After a while, Was thinking about it so I tried the update again, and luckily it worked! I did absolutely nothing different. It was very strange... Then for my cheese grater I tried, got the error message, and thought to my self "Not again!". This time I wasn't waiting around three months to try and install it again. So I took the easy route and just popped my old 24 iMac's hard drive into it and it works just fine.

I had the same problem with an iMac. Tried everything, including both your "solutions" and none of them worked. Isn't the time setting, isn't the expired certificate. It's a download problem from Apple's server. Gotta go directly to an APple Store and get them to give you (from the store's source) the installer for EL Cap. That is the only solution.

[@Steveos312]

This is why I install once, install all applications, configure prefs; I then "FREEZE" the Mac by booting in via another partition and create a DMG on Disk Utility. This is called "Imaging" and keeping YOUR OWN copy of OS X will save on your WAN bill; and your own sanity. It's no longer really supported as a practice by Apple; but if you have any pre 2016 Macs; this has worked well (and can work in Power PC Macs as well!)

[@jesusmoronta2514]

The thick progress bar did appear while updating to MacOS High Sierra. This can happen to 2011 MacBook Pros. This means that it is updating or in a other mode that can happen while changing the OS. This is a firmware update on update.

The date and time thing worked for me a few times. It's hit or miss. The best way I've found is to create a USB installer of Mavericks, then put the El Cap installer in applications and Install El Cap from there. Bit of a pain but It's always works.

[@googo151]

Before I saw this reply, I said the same thing.

[@DonovanColbert]

Do firmware updates come down automatically with OS X when you select Software Update from the Apple menu? I picked up a bricked 2011 i7 (with the Radeon GPU). It powered up, but the owner told me "it only runs Windows or Linux." Sure enough, there was a Windows install on it. I set about trying to do Internet Recovery - and was getting errors, "The Required Packages Could Not Be Installed," or some such. Messed around with it for a couple of days, and finally I found an image of lion floating around the Internets - made a USB disk and it installed. But the goal is to get to High Sierra. So, High Sierra requires you to have at least El Capitan. So I tried El Capitan, downloading the .dmg from Apple and installing it from the Application folder - and it was taking forever to install, just creeping along, and so I shut down and it threw me back into the state I was in previously - *and* my Lion USB drive also couldn't install. I was up until 3 AM, wiping the drive on a Windows system, removing the efi partition... everything failing - then as a last ditch effort I zapped PRAM, and the install worked. I suspect something like this is how the machine initially got into this state - and I suspect it has been in this state for a while, as the Radeon seems fine. So, now I'm back at El Capitan. Same download - createmedia to create a USB thumbdrive for El Capitan - it loads, I can get into the tools like Terminal, but I cannot click to start the El Capitan install program, or ANYTHING on the main menu (Disk Utilities, online help, etc...) I ran Software Update under Lion and it downloaded a bunch of things - but I wasn't sure if it downloads system firmware patches. BUT... I've downloaded the firmware from Apple and tried to install it, and it throws up a message that the install isn't for this system (2.4 and 2.7 - which are BOTH supposed to be for the Late-2011 Mac i7 according to www.macobserver.com/tmo/article/apple_updates_firmware_for_2011_macbook_pro_air_imac_mac_mini ) Other sites say that if a firmware won't install, you're already up to date. But system profiler says Boot Rom version MBP81-0047.b27 and SMC Version 1.69f And I feel like that is NOT updated from what I've read? But it would sure make life easier if Apple made the information match... if you call it 2.7 in the download, why not call it 2.7 in system profiler? Anyhow, that is where I'm at - I've got a MBP 2011 brought back from the dead running a dubious copy of Lion that can't seem to run ANYTHING else except Windows or Linux - and these are my questions. If anyone has any answers, I'd be grateful AF. :)

[@kpnorkin]

Follow up to report success. As I said before, neither Recovery Mode into El Capitan nor Internet Recovery Mode into High Sierra worked. Bootable High Sierra USB stick did not work. What DID work was an unexpired El Capitan installer from Apple's website as you mentioned just past 5 minutes. I made a bootable USB of this using DiskMaker X instead of terminal Since I had probably downloaded the High Sierra installer (which didn't work) from the same Apple page, It appears that my old MacBook Pro simply did not want to go straight to High Sierra. I assume that with El Capitan installed, updated and running, I'll now be able to upgrade to High Sierra, even if I have to get there through Sierra first. I'm happy I didn't have to go into Terminal. It seems that a fresh unexpired installer accomplishes the same thing as setting back the installer's clock. Thanks for the video and explanation.

Can you make a video for if it says “File system verify or repair failed”? I have a brand new hard drive and I’ve tried so many things already and it’s still not working. I have a 2012 MacBook Pro.

Dude... that mac can support imaging. Are you familiar of making system images in a custom manner? And have a large hard disk drive to store them all?
