Although there are some performance issues with Duet, to display text (which is what I do) is just fine. Now I can have the browser, the IDE (PyCharm if you are wondering) and iTerm 2.
Since is another screen attached to the laptop you can use it to display any other thing that is being processed by your main computer, and can move apps between the screens with no problem at all.
A bit of humor about the new MacBook Pro. Obviously this guy is not an Apple engineer but make it funny. Or you might want to see him talk about the MacBook (that one that have only one port)
Well, not really forgotten, the thing is that I was unable to access to recovery or boot to another disk (like the recovery in time machine disks) because the Mac have the firmware password.
Why a firmware password?. Well, to protect your machine in case of being stolen/lost. The password will stop the boot process if the boot disk is not the one that was present when the password was set. Also stop booting to recovery/USB/Super Drive.
This firmware plus FileVault (disk encryption) will prevent getting your data or use your mac without permission.
There is also a second firmware password set when you use “Find my Mac” which locks your computer and asks for a 4 digit password at boot as soon as you report your mac as lost/stolen in iCloud.
If you loose your firmware password then you’ll have to go to an Apple authorized specialist with proof of ownership, then they can remove the password, but in my case that means 6 hours driving to the nearest apple support specialist ?.
I used all the passwords that I remember, none seemed to work… until I realized that the password was entered with a Spanish keyboard layout and the password entry have no choice over the layout, English only. So the special (nonascii) characters didn’t match.
I had to discover the keys to write the password in English layout and taraaaa!!
I didn’t removed the password, but now I know why it wasn’t working.
The layout thing.. I hope it helps you if you are in the same situation as I was.
