MAC OS X Yosemite Upgrade Issues
I was excited when the announcement of Mac OS X Yosemite Beta was out and open to public testing, but I was not able to download, I am guessing because there are many people like myself who wants to get their hands on the new OS from Apple and their server was not able to accommodate the demand. And yesterday I decided to give it a try and I encountered many issues. It served it’s purpose as Beta and the question now is how do you get back all those things that were working before the upgrade? There will be many people who will surely get into trouble if they were overtaken by their excitement and may have not fully understood the term beta or testing. So in this article I will share what issues I encountered and how I fixed those issues.
1. Final Cut Pro X 9.x – I have projects that heavily depends in this Application and apparently it did not worked after the upgrade.
2. External Monitor – Sometimes it works but most of the time it does not.
3. WiFi – does not re-connect automatically after reboot and sometimes turns off unpredictably.
4. Boot Time – Really Slow and kernel panic where I have to press the power button couple of times for it to start properly.
5. Dual Boot – I am on dual boot with LINUX using reFind and it is not working anymore even when reFind is re-installed.
6. Encrypted Hard Drive Partition – It became an unknown partition type with FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF GUID code
1. Upgrade to Final Cut Pro 10.1.3
2. I am not sure what the issue is so my solution was to downgrade back to Mavericks.
3. Downgrade to Mavericks.
4. Same as 2 and 3.
5. I was too lazy to figure out what’s wrong, I played with gdisk changing some configuration but it’s taking sometime so I decided to reinstall.
6. Follow the steps below:
6.1. Download and install gdisk
6.2 Let’s identify the partition by doing the below:
sudo gpt show disk0
As you can see under index 5 (partition number) it says GPT part – FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF
Now we know that it is the unknown partition!
6.3 Let’s change the partition type code to AF05 or “Apple Core Storage”
sudo gdisk /dev/disk0
This is to verify the partition again 🙂 in case you lost your focus like mine.
We will copy the code of the MAC OS X Partition!
Note: The name of your partition might be different so please be careful.
Press: t – to change the partition type code.
Press: L (optional) – to show codes
Then Type: AF05
Press: w – to save the changes.
The hard drive automatically mounted and asked for my password.
