re installing OSX problems

Does anyone know why its becoming nearly impossible to do fresh installs of OS-X on older Mac Systems.

I have had a collection of various versions of OS-X installs set up on USB sticks. Have been using them with no bother for the past 5 + years. In the last 6-12 months they have all stopped working.

When I try to re-burn them and use them the Mac system is saying the install has become corrupt.

The current issue is with a customers MacBook Pro, the 500GB mechanical HDD has died. Have fitted a 480GB SSD and tried using the internet recovery to install Mountain Lion.

After formatting the drive and starting the install i get a timer stating its going to take -2,393,938,938 and 8 minutes. After about 2mins it pops up saying Can’t download the additional components needed to install Mac OS-X. I have tried it with a standard mechanical HDD as well as the SSD.

I am having this problem as well.

I have erased the drive and indeed get the can't download additional components needed msg.

My question is how do I download the new os if I no longer have a functional MacBook Air (2011)

I can only book to utilities screen and we know the reinstall option will not work.

Pls help all I wanted was a fresh install to clear the machine.

I'm in the exact same boat as Chris Barlow. I have wiped the drive on my Mac mini and just want to install a fresh copy of Lion on it but I get the same error message. Even Apple can't (or won't) assist with this.

- de

Also have this issue! I'm wondering if Apple stopped hosting the OS X software components...

- de

Apple no longer supports older OS-X releases older than El Capitan and sometime this year that too will be retired.

The only way to install older OS-X releases (the OS that came with your Mac) is to create a bootable OS installer with the OS you want. As an example I just setup someone with Lion using a USB thumb drive after I altered the system date so the installer is fooled!

Review my answer below for all of the details!

- de

Sorry Dan, altering the date via terminal was a lost of time. It didn't work for me . What did work was using a bootable usb.

In a friend's Mac, download the desired OS installer (High Sierra in my case for my MacBook Pro Late 2011 - google "How to Download a Full macOS High Sierra Installer App") and create the bootable USB, HDD or even SSD with Disk Creator (2 steps very friendly freeware tool - google "disk creator").

Just forget the internet recovery mode and don't bother with network certificate issues...

Hope you recover your machines!

You’re hitting an expired certificate issue! Here’s more on it If you've got an old macOS install image, it will probably stop working today

Apple has been doing this for years! You mostly on hit this issue on systems which can’t support newer OS’s. As an example I had to re-install Lion for someone as they just didn’t want anything newer (90 year old lady) who just didn’t want to relearn how to do things or have the will to update her apps.

The issue you face with the newer macOS’s is Apple didn’t update the certificate which is why this has become more of an issue as of late. Here’s the updated installers:

In all of these just jump down to Step 4 to get to the URL link for the OS image.

Apple did not alter the older images in their downloads. Some Internet recovery images likewise have not been updated.

OK, What about the older ones!

Not to fear! You can still install the OS. The trick is back dating the systems clock! Alter the Date & Time setting from auto set to manual and then alter the date to a year that is within the given OS’s release window. Now your older OS installer thumb drives will work! Just remember to re-set the Date back to the correct year and set it back to auto.

So when Apple is telling people the images are "damaged" they are lying, they are not damaged at all.

Persuading you to get a newer OS or system for sure! ;-}

@danj

Thank you for confirming my suspicions and helping me get round it.

what about creating a bootable media?

i have created a couple of new usb bootable sticks using Transmac.

and on this slightly more mature macbook its not even seeing it to boot from.

should transmac just work, or can you recommend some other ways of creating the bootable media

i have not tried transmac with the download links you have provided. so i will give it a whirl.

the dmg files i had downloaded were from 3rd party hosting sites or where people have uploaded their own DMG files to online hosting sites.

- de

You can't trust this off the wall sites! Often times they have been compromised! Download the macOS only from Apple you don't waste your time or worse yet infect your system with spyware/malware!

I personally don't use Transmac I know its a bit tricky I use a Mac running macOS to create my installers.

- de

@danj

may i ask how you are creating your installers?

You might have install images that Apple considers outdated. Try turning off Wifi and take Mac’s clocks backwards in the past. You can either do that from a working external disk or you’ll have to do it from the terminal using the Set Date command, you can easily find the correct syntax with a google search. Do not let Wifi working or it will adjust the time again when the installer calls Apple servers.

Did you use the links I posted? They are the newer image files so you don't need to mess with the date setting.

If you are using something older than Sierra then you'll need to use the alternate method. But you can't use the over the net recovery! While you might have altered your systems date the network date will interfere! You need to create a bootable OS installer USB drive or if you have a 2010 or older system you'll need to setup a FireWire drive or Optical drive image.

- de

I've had same problem with a MacBook Pro mid 2012

Tried this method with setting up time and date and it didn't help. I've also tried booting from bootable USB with macOS Lion 10.7.2-10.7.3, Mojave, Catalina, and El Capitan until

I've found Yosemite created bootable USB and installed macOS with no problems at all in about 20 mins. It seems that you have to try different versions of macOS until you find suitable for your mac to boot.

- de

Just did two systems installed Mojave without any problems on both a 13" & 15" 2012 MacBook Pro's

Sounds like your OS installer drive was not setup properly.

- de

@danj "You need to create a bootable OS installer USB drive or if you have a 2010 or older system you'll need to setup a FireWire drive or Optical drive image." Are you saying a bootable USB drive wont work for 2010 or older? I created one for my 2011 Macbook Pro and it's not giving me the option at bootup, although I can see it in the Disk Utility after running the internet option.

- de

Not all MacBooks Pro's are able to boot up under USB. The 2010 and newer are. Basically, the systems which offer USB 2.1 have the ability to boot from USB.

To make things easier and faster I just prefer FireWire drives on these older systems as their USB port are either USB 1.1 or 2.0 or 2.1 all of which are slow, over what the FireWire offers. And besides, I don't need to worry about the nitty gritty of remembering which ones ports support boot.

@dan I’m basically in the same boat as everyone here (wiped 2011-12 MacBook Pro, trying to reinstall OS) and I’m to the point where I am rebooting and entering disk utility. I have an OSX LION install file on a thumb drive, but I cannot figure out the next step. How do you access the file on the thumb drive? I go into disk utility and the only option I see there is to restore and create a new disk image. I’ve done that, but now I’m at a roadblock

Not sure what you have here. Double clicking on the OS installer file will launch it. If that won't work then you don't have a working installer.

You may need to breakdown and buy Lion OS-X 10.7 CD if you need to stick with Lion. I strongly recommend you get to Sierra as thats the best OS for your system.

If you have access to a second Mac you should be able to create a bootable OS installer following the guide and OS download I posted above. Make sure you format the USB thumb drive to GUID Journaled file system before you start.

- de

@dan thanks, just to confirm, you’re double clicking on the os installer in the disk utility window, correct? Is there somewhere else I should be performing this? I didn’t see it specified in the guideline above

I bought lion through Apple but they haven’t sent me the link yet. Do you have to unpack the .dmg file before putting it on the thumb drive? Sorry, a little new to this

Thanks again

- de

Richard Gomez -

The physical file within your drive double click on it, The Installer file is just any other installer. You don’t use Disk Utility to run it.

Apple should send you a CD not a URL link! You need the physical media (CD)

It sounds like you're stuck in a catch22 condition!

You altered the date but as soon as you connect to the internet the time servers will correct it! So you are never able to get past the certificate check which is what's blocking you.

You need to create an external USB thumb drive OS installer. Which you'll use so the date is not changed! You also are limited on which macOS you can use.

Had the same issue with Macbook Pro Mid 2012 my machine just didn’t like the update. Trying to go back to El Capitan from Catalina I got the same error message using internet recovery or using a USB install stick “ Can’t download the additional components needed to install Mac OS-X” . Changing the clock time back to an earlier date in terminal as Dan & abraman suggested did the trick. I already erased my HD so needed to launch terminal during recovery/install and make sure you remember to turn off wi-fi if you previously tried recovery from internet. My install only took about 20min once I changed the time.

Great info on this post thanks for the help

@kcillor - You hit an expired certificate issue, Apple goofed! They forgot to reset it the last update. Here's more on it If you've got an old macOS install image, it will probably stop working today. You'll need this install image How to upgrade to OS-X El Capitan jump down to step 4 for the link.

@Special McGhee - Which macOS are you trying to install?

- de

Dan- are you saying that if I make a new usb install stick from the download you suggested (apple support) that I won't have to adjust the clock the next time I do an install?

- de

@kcillor - Yep!

I haven't had a chance to check it but a friend of mine told me Apple fixed this image as well. I was a bit surprised as its on the edge of supported.

I don’t have an answer but I’m having the same issue. I’m able to get through the internet recovery (command-option-r) and get to the utilities. I’ve erased my HD and when I go to install Lion it says I need 999.35 GB but have 998.68 available. Then I get the error message ‘Can’t download the additional components needed to install Mac OS X. Does this sound like I just don’t have enough space? I’m not having any success creating an external installation (don’t have a big enough flash drive and no external hard drives). Any thoughts are appreciated! I’m on my 7th hour trying to get my 2011 imac to work :)

Also don't have an answer but I have got a completely wiped iMac late 2011 trying to install Lion (or just any OS for that matter!). Read through all the comments, tried the date/time fix in Terminal but no year between 2009 to now makes any difference, same error- “cant download additional components needed to install Mac OS". And if connecting to WIFI overrides the date/time fix then how are you supposed to install the OS? Connecting to Safari via MAC Utilities and downloading it doesn't work either because you download the dmg file but because theres no OS, theres nothing to then open the dmg file?!?! Help!

UPDATE: struggled for a week trying to mess about with it, went on to Amazon, ordered a USB drive, arrived 3 days later, plugged in, held down command key as it booted up, clicked on the USB drive and 15 mins later OS installed and sorted, no fuss at all!! Everyone go and buy this : https://www.amazon.co.uk/Bootable-Instal... (check the OS will work for your iMac year) hopefully this helps everyone as it did me!

Are you sure about the link?

All they are doing is selling you what I was trying to get you to create. Awfully expensive and your don't know if the OS is clean which could put your system at risk (malware).

I'm sure you can find someone with a Mac nearby that can help you. This isn't that hard to setup with an another Mac.

I started from scratch on the boot disk using my other MacBook Pro and a YouTube video to help me with the terminal coding. After recreating the boot disk (it took awhile to churn through 6 Gb) I was able to boot from disk and reinstall High Sierra on the ailing MBP. All went well last night as I reloaded software I needed, including Microsoft Office stuff, Dropbox, and Chrome. All was fine, slow, but fine. Today. Won’t boot all the way, won’t boot in safe mode, and there are pastel horizontal lines on the screen. The machine is ten years old and I have kids at home doing schooling (Honestly, I think this is what wore it out!) who need a computer, so my ultimate solution was to buy a new MB Air, on sale for $800 at BestBuy. I briefly considered taking the old MBP in to a shop, but after ten years I think it’s time to let it go. Thanks for all the help on this thread!

I have tried the following

1) internet recovery, same issue as Stuart

2) made a bootable USB with High Sierra in it (would not install onto MacBook)

Any ideas? Thanks in advance,

Hi,

When you mention:

2) made a bootable USB with High Sierra in it (would not install onto MacBook)

What do you mean?

Do you get to see the bootable USB when starting your mac pressing the Option key?

Hi Ricardo,

I created the bootable USB with High Sierra on my 2016 MacBook Pro 13inch Touchbar (has Sierra OS) (made via Terminal).

I did get the bootable USB, it was even installing it on the SSD but at the very end, it wouldn't install and gave a message saying it couldn't install
