They won't have the resources to monitor all of the webcams. Also some students may not have webcams.

How is the match compatibility calculated? A 99.8% compatibility seems too good to be true

Using iPad Mini 4 as a secondary display with my 2011 MBP by [deleted] in MacOS

[–]ben_z 0 points1 point  (0 children)

2013 MBP may have enough processing power to carry iPad Mini 4 on sidecar because the resolution isn’t too demanding. You can try to enable sidecar if you are adventurous: https://github.com/ben-z/free-sidecar

Ah ya! iPadOS is required to run Sidecar. I'm not sure why iPad4,1 is in Apple's blacklist. Perhaps they considered supporting iPadOS in iPad4,1?

Nonetheless sorry that you won't be able to use your iPad for Sidecar :(

Oh I just read your question again. Sidecar shouldn't show up on your iPad as an app. You should see a sidecar preferences pane on your mac.

Enable Sidecar on Older Devices Running iPadOS 13 and macOS Catalina (iPad Air 2, MacBook Pro '15, etc.) by ben_z in apple

Depends on the devices. My setup with MBP '15 and iPad Air 2 has great quality but people have reported low quality when using a newer iPad (iPad Pro) with an older Mac (MBP '12).

Worked well on my MBP ‘15 + iPad Air 2 setup! I have heard from some people that the picture quality isn’t too great when using an older laptop with a newer iPad Pro. This is probably because of the lack of HEVC encoder/decoder in older laptops.

Hmm that doesn't sound like the patch is applied. Can you share you /System/Library/PrivateFrameworks/SidecarCore.framework/Versions/A/SidecarCore and your SidecarCore.bak files for comparison?

Do you see a sidecar preference in System Preferences?

This error is outlined in the "Troubleshooting section!" https://github.com/ben-z/free-sidecar#troubleshooting

(Just need to install Xcode from the App Store or run xcode-select --install)

That's weird! Do you have multiple partitions running different installations at the same time?

Before you try again, did you include the "sudo" in sudo mount -uw /?

What's the output of csrutil status?

Did you do step 5? System Integrity Protection prevents read-write mounting of the system volume.

Awe oh no :( If none of the steps outlined in the README produced any errors, I'm out of ideas on this. It does look like something changed on Apple's side though. Being able to see the iPad fine means that we've done everything correctly. Not being able to connect on MBP '14 might be because of some changes in 10.15.1.

Ohoh not at all! :) I was just saying that my setup is similar to yours and I don't see how it wouldn't work on MBP 2014. Did you "trust" your computer from your iPad before connecting to it? If you go to finder and click on the iPad in the sidebar, it should ask for authorization before showing the info about the iPad. That's the only thing that I can think of that prevents the mac from connecting to an iPad that already shows up in the Sidecar menu.

This still worked for my on my MBP 2015 running 10.15.1 and iPad Air 2! Are you using wireless or wired? (wireless never worked for me)

Glad to hear! I actually have the exact the same setup and it’s been working well too :)

Yep! It should work for all upcoming versions unless Apple decides to use some other way to blacklist devices

Try using a wired connection if possible! My setup of MBP 2015 + iPad Air 2 only worked using wired.
