Help with turning on server performance mode in 10.15

[Michael Cavanagh]

I have a mac pro 5.1 running Opencore 0.7.5  and I need to set the boot-args performance mode on to fix a networking SMB bug in 10.15 But I cant seem to change the setting not matter what I try.

 

I have edited my config.plist to include the line -serverperfmode=1 under boot-args I have also tried doing it via command line 

 

sudo nvram boot-args="serverperfmode=1 $(nvram boot-args 2>/dev/null | cut -f 2-)"

 

I have also tried doing it in recovery mode and ensure my SIP is disabled. not matter what I try I cant get performance mode to enable.

 

when trying on the command line I get this:

 

nvram: Error setting variable - 'boot-args': (iokit/common) general error

 

when I edited the config.plist to include "-serverperfmode=1" and reboot I checked to see if it worked by using the "nvram boot-args" command it seems to work as it returns this:

 

-lilubetaall -wegbeta agdpmod=pikera shikigva=80 unfairgva=1 mbasd=1 -wegtree -no_compat_check no32exec=0 -serverperfmode=1

 

however when checking with the command "serverinfo --perfmode" I get this: 

 

Server performance mode is NOT enabled

 

what am I doing wrong?

 

one though I had was to add this line to the config.plist file under boot-args

 

"serverperfmode=1 $(nvram boot-args 2>/dev/null | cut -f 2-)"

 

would that work?

 

Thanks so much for you help!
