The en1 is my wifi card, to see the interfaces you can execute this: sudo networksetup -listnetworkserviceorder This error is described on Github, I can’t solve it yet but there is a work around using the terminal to connect it with this command: sudo networksetup -setairportnetwork en1 To test it, I’ve installed macOS Big Sur with Open Core Legacy Patcher but there is a lot of issues and it has a poor performance, so I’m back to previous version with macOS Catalina and the experience is so smooth, you can see in the previous image the evidence.īut there is an issue, it can’t connect to a hidden wifi connection, in the top bar the near SSID are detected but when I’ve try to connect to my wifi that can’t be established. In this entry I’m going to share my experience.įirst, is truth, the max RAM supported is up to 16 GB of 1600MHz, I’ve bought in amazon these modules, note they are a DDR3L with support 1.35V or 1.5V and it works great. I know this is a very old device, in order to not dispose it I was thinking to install a linux system on it, but I’ve decided to given a second chance upgrading the RAM and testing with an unsupported macOS.

I’ve an old MacBook Pro (13-inch, Early 2011), according to the apple support the last supported OS is macOS High Sierra 10.13.2 and the technical specs indicates the max upgradable memory is up to 8GB (two 4GB SO-DIMMs) of 1333MHz DDR3 SDRAM.īut reading on internet I’ve found that can be upgradable up to 16GB of 1600MHz DDR3L SDRAM and it’s possible to install a superior version of macOS using a non official patches and installers, like Catalina Patcher or Open Legacy Core Patcher.
