I just got interested in linux systems and wanted to try Ubuntu on my macbook.

I watched some videos about the installation and finally installed Ubuntu 19.04 on my MacBook Pro late 2015. But then I realized that the boot-loader doesn't work the same way like with mac os' bootcamp for windows.

I searched the web and found the rEFInd to choose whether to boot mac os or Ubuntu. I tried it and it worked, but I didn't like rEFInd and removed it.

Then I started googling again and found a solution on this blog Dual-Booting OS X or macOS with Linux without rEFInd.

But there it says "You can skip steps 5 and 6 for Ubuntu 18 or above". However, I didn't skip them and created a new EFI directory (I guess, and I think this is the problem).

Then I restarted my computer and Ubuntu booted. Then I restarted again and this time held the option-key to boot from Mac OS, but there was the only option to boot from Ubuntu.

On Ubuntu I can still see my partition with the Mac OS in it, but I can't access it.

So, I'm asking you if you can help me to come up with a solution to boot back from my existing Mac OS, because I also hesitated to back it up and now I feel very miserable. I will be very thankful if you can show me a solution.

  When you installed Ubuntu, did it detect that there was already an existing operating system? During the partition/formatting options it should have alerted you to this. The GRUB bootloader would have been installed and when you boot to Ubuntu before it actually loads Ubuntu, you would have a choice of OS. If you allowed the installer to write over the whole disk, then MacOS would be gone and you'll need to reinstall it.
