But converts the.pkg to the Install OS X El Capitan.app which you will find in your Applications folder, it should be 6.2GBs in size. To start the installation of El Capitan double click on the Install OS X El Capitan.app. The copy of the install app self deletes after installing El Capitan, so make sure you keep a copy of the InstallMacOSX.dmg. El Capitan Installer is the post version to the Yosemite, and it was built by adding up more improvements to the Yosemite. In this version of the Mac operating system, the Apple Inc. Has focused on the performance, stability, and security of the computer. Anyone who is interested can download it on the Mac PC.
Mac Os El Capitan Installer
- I am trying to upgrade an older iMac (2008) from OS 10.6.8 to El Capitan for a disabled client who really needs to use a Mac instead of a PC!
- EveryMac says it can handle El Capitan if I upgrade RAM. It has 4GB now.
- I have an Installer file from my own Mac (always keep them when I upgrade). I made a bootable flash installer that mounts and seems to have the proper files, but it won't show up on either Mac on restart holding option key; nor in the Startup Disk list. So, I figured writing to the flash drive must have failed.
- I partitioned an external hard drive and redid this:
'sudo /Applications/Install OS X El Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install OS X El Capitan.app'
- It seems to work (again) in Finder AND it shows up as a boot option on restart (holding option key), but when I select Install OS X I get an error that the installer cannot be verified. I can't get it to work.
- So, I figured my installer must have gone bad, even though I successfully upgraded my own Mac with it, and have since upgraded mine to Sierra.
- Using the App Store I can get to El Capitan, but it will not allow me to download it on my Mac because the system is too new, and I don't want to download it to the old Mac because I want to use an external drive to do a clean install; not an upgrade on the old one.
- Any advice?
IMAC (RETINA 5K, 27-INCH, LATE 2015), macOS Sierra (10.12.3)
