MidiKeys is not happy with Big Sur

[curieux88]

it crashes immediately. does anyone have any similar issue?

Thanks a lot for the report! I hadn't installed macOS 11 yet due to concerns about privacy, but I'll get it set up in a VM so I can test MidiKeys.

I upgraded over the weekend and found the same trouble. Crashes immediately on launch. I have attached the Problem Report - hope it helps!

I've created two pull requests that solve the issue for me:

• Use NSGradient over old CTGradient that crashes #11 solves a crash in CTGradient by using NSGradient to do the same work
• Remove ShortcutRecorder and Sparkle dependency until fixed #12 solves a startup issue due to unsigned libraries being loaded

I think the first should be fine to merge, but the second one is a hack just to get the app to run. It really needs someone to find the right magic settings. I don't need the shortcut functionality so I'm content with the result for now.

Now, how to release a build for Big Sur is a difficult question given that patch #12 removes Sparkle… If I release v1.9.1 for pre-Big Sur OS versions, then it will disable future software updates for folks not moving to Big Sur. Otoh, users who are going to move to Big Sur won't see that an update is available prior to moving. Sparkle supports updates that are available only on a given OS version—but since MidiKeys doesn't run at all on Big Sur that's not any help. ☹️

For now my plan is to just make a Big Sur-enabled v1.9.1a1 available via the GitHub project. Then hopefully I can get a full fix in place before long.

Thanks again @bradhowes for helping out!

Could you kindly release v1.9.1a1?

+1! i tried compiling it myself but i am having problems getting the submodule

[bradhowes]

I just tried compiling and running without a problem:

% git clone https://github.com/flit/MidiKeys.git
% cd MidiKeys
% xcodebuild -allowProvisioningUpdates DEVELOPMENT_TEAM="UP********E" -scheme "MidiKeys" build
% open DerivedData/MidiKeys/Build/Products/Debug/MidiKeys.app

DEVELOPMENT_TEAM needs to be set to your own value -- best done in Xcode. I just did the above to show that I was able to get a build without issue.

@mattingalls What issue did you have?

[bradhowes]

Bah! I tried again and this time I got your issue @mattingalls. This does the build:

% git clone https://github.com/flit/MidiKeys.git
% cd MidiKeys
% git submodule init
% git submodule update
% xcodebuild -workspace MidiKeys.xcworkspace -allowProvisioningUpdates DEVELOPMENT_TEAM="UP********E" -scheme "MidiKeys"
% open DerivedData/MidiKeys/Build/Products/Debug/MidiKeys.app

So you were missing the git commands after installing. Still perplexed why my earlier attempt worked. I must have not really deleted MidiKeys directory when I thought I did before cloning.

[bradhowes]

I've uploaded the build I made with the above - https://github.com/bradhowes/MidiKeys/releases/tag/v1.9.1-bh

[flit]

Here's the "official" version 1.9.1a1 notarized release:
https://github.com/flit/MidiKeys/releases/tag/v1.9.1a1

Apologies I hadn't released the build yet!

Finally got out the final 1.9.1 release with Sparkle and ShortcutRecorder integrated. This version is now universal for x86_64 and AArch64, tested on my MacBook Air M1 and other systems. There are some additional issues I'm sure everyone has also noticed on Big Sur, for which issues have been created. Thanks again @bradhowes for helping out so quickly!
