You can always try the fully manual way

I got Spectralayers 12 by doing what done84 did. The new updated script didn't work - simply because of zero information on what 'source file' was supposed to be. To do this I installed the latest SL12 installer AND patch (you have to allow in security settings), installed the steinberg licence manager from their website, then ran the above commands one at a time (like done84). I found you have to be offline when running SL12 or it doesn't work and you have to do it all again. But, working 100% M4 Sequoia without touching SIP


EDIT: If you deny everything with little snitch it's fine too

Thanks for your reply
I've followed all steps, the only differences was were I have to choose 'use system standard’ because I didn't see that option, instead it was ‘use system default’
The thing is that after running the command in terminal SL12 still doesn't work with SIP enable
I'll double check the manual way to see what am I missing

PS: what's the order (sequences) of steps to get this working?
Mine was:

1. Installed the crack from the sister site S(pectraLayers_Pro_v12.0_Installer_mac) that comes with a Patch that requires SIP disable
2. Then I follow your instructions modifying the cubase patch to SpectraLayer 12
3. Installed the provided certificates
4. Run The modified Patch command didn't work
5. I create my own Certificate following instruction, but here I encounter a problem (I guess) in Xcode I don't have ‘use system standard’ option, it's ‘use system default’ instead. So I "Trust" everything in there and got a "Certificate" (not with a green check but a Blue + sign)
6. I run the SpectraLayer 12 Patch command again but didn't work either

Is it right?

Thanks again

 

Thanks for your reply
Correct, no idea what is the 'Source file' I used the SpectraLayers file located within SpectraLayers 12>Contents>MacOS>SpectraLayers but not sure if this could be the reason it didn't worked for me
Beside that what about the steps from scratch, are they any relevant? I would say yes, so ere the steps I took OK?

PD: I've tried once Little Snitch but it was too complicated for my knowledge in security/firewall and the like so I removed it. But if it that useful to get this SL12 running with SIP enable, I'd reconsider it
