No packages were eligible for install. This is what it looks like in the installer. Upon seeing this I went 'HUH?' Because the installation was from a thumb drive I'd used many times to install Mac OS X (El Capitan) successfully. The above image came from an attempt to install El Capitan. I just got the following message, macOS could not be. The Mojave 10.14.1 update does NOT install properly on unsupported machines, and could result in an unbootable OS. If you want to install the 10.14.1 update (and are not currently running 10.14.1), perform the following steps. The attempt to install data.table failed due to a problem compiling the package from source. Before trying to fix that, though, you might try installing the binary (already compiled) version that's available — it's not that much older than the source version. To try this, run: install.packages('data.table', type = 'binary'). Sep 22, 2021 Os X Could Not Be Installed On This Computer No Packages Were Eligible For Install Tags: Mac OS X A key step for upgrading the disk on a MacBook Pro is to install a new operating system on the new drive, and then use Migration Assistant to copy over the old data.
If you ever get this error while attempting to install OS X, you will likely need to set the date using terminal.A new version of macOS is always exciting. But it can quickly become frustrating if, instead of being presented with a brand new Mac, ready to use, you see an error message like “macOS could not be installed on your computer.” Fortunately, you can do lots of things to fix the problem, so let’s get started.
It’s essential that before you perform any major upgrade, say from Catalina to Big Sur, that you backup your Mac. One of the steps described below involves a complete reinstall of the operating system, resulting in erasing data from your drive. It’s best to do the backup using Time Machine, as you can then use Recovery Mode to restore your Mac from the backup. But if you don’t want to use Time Machine, create a bootable clone of your startup disk using a tool like SuperDuper or Carbon Copy Cloner.
There are several reasons you might see this error message. Here are some of the most common.
Check if your Mac is compatible with the version of macOS you’re trying to install. The best way to do that is to launch the App Store app, search for the macOS version you’re trying to install, and scroll down the Compatibility section. You should see a message that says, “works on this Mac.” Alternatively, go to Apple’s website support pages and search for the minimum system requirements. You might need to reboot in Safe mode, see below, to check because if you do a normal restart, your Mac may immediately relaunch the installer.
Safe mode disables startup items, launch agents, and everything else except the bare minimum macOS needs to function. Restart your Mac from the Apple menu or by holding down the power button, and press Shift until you see the Apple logo.
If the problem were that launch agents or daemons were interfering with the upgrade, Safe mode would fix that. If it works, you should restart your Mac normally after the installation and remove any launch agents and daemons you don’t need.
The simplest way to remove launch agents is to use CleanMyMac X.
Here’s how:
You’ll need up to 20GB of free space on your main drive to download and install an update to macOS. If you don’t have that much free space, it’s time to clear out the junk and free up space. I’ve found that the quickest and easiest way to do that is to use a popular app CleanMyMac X by MacPaw. It can free up tons of gigabytes of space with a couple of clicks.
Install CleanMyMac X, then launch it — download free edition here.
The NVRAM on your Mac stores data even after your Mac shuts down or restarts, unlike regular RAM, which is flushed every time you restart. NVRAM persists, thanks to a small amount of power supplied by your Mac’s internal battery. Resetting NVRAM rarely has any effect, but it can do in some situations, and as it won’t do any harm, it’s worth trying. It’s quite tricky to do, so that you might need some help.
Restart your Mac while holding the Command + Option (Alt) + P + R keys and wait until you hear a startup chime. It may take a little longer than normal to restart twice, but the NVRAM will have reset once it's done.
If you can restart in Safe mode and quit the installer, try downloading the combo updater from Apple’s website. The combo updater contains all the files necessary to install macOS on all Macs, whereas the version downloaded from the App Store only has the files for your specific Mac. It may be that the combo updater works, where the Mac App Store version doesn’t.
This is the last resort if nothing else works.
There are a number of things you can do to fix your Mac when you see the message: “macOS could not be installed on your computer.” If the problem is that you don’t have enough space, you can use CleanMyMac X to get rid of files you don’t need. Otherwise, go through the above steps one at a time until you’re able to install a new version or update to macOS.
