Running Snow Leopard on a Late 2011 Macbook Pro to avoid dead discrete GPU.

I have a collection of old firewire devices and am going to have a go running my problematic MacBook as the controller/interface for these devices,

The plan is to run this MacBook only using integraded graphics Intel HD3000 (bypassing the AMD Radeon 6770M).

As these devices vary in age it also makes sense to use older MacOS versions.

Running the MacBook seems possible by removing kexts from the OS to prevent ever switching, but I am also looking for device compatibility so I will try installing Snow Leopard, which shouldn't require removing kexts, as it does not include support for the 6770M.

A little history
2010 MacBook Pro's featured both Core2Duo's and the i5/7 chips, and were shipped with 10.6.3.
Early 2011- 2nd generation i5/7, and were shipped with 10.6.6.
Late 2011 - 2nd generation 15/7, shipped with 10.7.2

Snow Leopard 10.6.6 seems to be the first version that supports the i7-2760QM, but cannot be installed directly.

The general technique is to create an Install Disk, boot a computer compatible with 10.6.7, then install it somewhere handy. Boot the MacBook in Target Disk mode, create an image and copy it across, physically move the hard drive. Many options.

My MacBook is already in some disrepair and no hard drive (HDD) installed (I also have no idea where the screws for the back cover are), so my choice was to put a handy HDD into an external enclosure and attached.

My process was to install 10.6 onto the only hand mac i had, which is a 2009 iMac with a Core2Duo processor. However at this point I wasn't fully versed in version history so after putting the HDD into the macbook, resulted in a kernel panic over cpu incompatibility.

panic(cpu 0 caller 0x558c2459: "Unsupported CPU: family = 0x06, model = 0x2a, stepping = 0x7"@/SourceCache/AppleIntelCPUPowerManagement/AppleIntelCPUPowerManagement-90/pmProcessor.c:210

Using Target Disk mode as an external drive for the old iMac, booting into 10.6 and updating to 10.6.8 fixed this issue.

It's all good and working well.

The next job is checking version histories for the various drivers and softwares such as MOTU AudioDesk and Cuemix.

basic setup openmediavault 6.5.0

once openmediavault is installed, basic guide to setup shared folder/drives.

#Enable Samba

Services > Smb/cifs > Settings > Enable
Apply

#Create User

Users > Users > Create (+) >
Save > Apply

#Mount each existing hd/partition

Storage > File Systems > MOUNT (>) > select hd/partition (add tag for useful display info)
Apply

#Create Shared Folders - I am not precious and simply sharing each partition.

Storage > Shared Folders > Create (+) >
Apply

**Name - name on network

File System - location of share. / for root of partition, /folder for location.**

#Add share to Samba

SMB/CIFS > Shares > Create (+) >
Apply

#Check User Permissions

Users > Users > click on user > Shared Folder Permissions (Folder/Key icon) >
Apply

-- Other Notes --

During install, if you skip any steps (I skipped network config), to use CLI command
# omv-firstai

When using terminal - by default mounted partitions are located in /srv by their UUID. There is a symlink plugin to make that easier using webGUI.

Reverse Osmosis Filter

 quote

The truth is that residential RO systems have a waste: pure water ratio that is set by the membrane supplier. The ‘waste’ water is required to flush the membrane and ensures that you can achieve a reasonable life span of 2-3 years before having to replace the membrane.  Any low ratio like 1:1 will ensure that the membrane needs to be replaced well before the typical life expectancy –ironically a bonus for the unscrupulous salesman who promised you the outrageous ratio.

Residential RO systems have a waste: pure water ratio of 3 to 5 to 1 (average 4:1) and the actual ratio should depend on a number of factors including water quality ,pH,  pressure and temperature.  In reality this ratio is set and predetermined, thanks to a flow restrictor that is sized according to the membrane output.

 arturia microbrute manuals.

today i learned the microbrute has various settings controlled via CC values. this is all hidden in the 

ARTURIA MICROBRUTE CONNECTION USER MANUAL.

now somewhat weirdly there is no evidence this file even exists on the official site and i've only come across it here

https://www.manualslib.com/manual/1172383/Arturia-Microbrute-Connection.html

also found the Oscillator Calibration document (if you ever wondered what the two microscrews are at the back of the unit?!) AND the Board Schematics here

https://www.synthxl.com/arturia-microbrute/

for ease of access, here is the list of Parameters available through CC

Parameter	Midi CC #	Value
Receive Channel	102	1 to 16, 17=All
Send Channel	103	1 to 16
Seq Retrig	104	0 to 41 = Reset. 42 to 83 = Legato. 84 to 127 = None.
Seq Play Mode	105	0 to 63 = Hold. 64 to 127 = Note On.
Next Seq Mode	106	0 to 41 = End. 42 to 83 = Instant Reset. 84 to 127 = Instant Continuous.
Seq Step Size	107	0 to 29 = ¼. 30 to 59 = 1/8. 60 to 89 = 1/16. 90 to 127 = 1/32.
Sync Source	108	0 to 41 = Auto. 42 to 83 = Int. 84 to 127 = Ext.
Env Legato Mode	109	0 to 63 = Off. 64 to 127 = On.
LFO Retrig Mode	110	0 to 63 = Off. 64 to 127 = On.
Note Priority	111	0 to 41 = Last. 42 to 83 = Low, 84 to 127 = High.
Velocity Curve	112	0 to 41 = Lin. 42 to 83 = Log. 84 to 127 = Anti Log.
Gate Length	113	0 to 41 = Short. 42 to 83 = Med. 84 to 127 = Long
Seq Step/Gate Mode	114	0 to 63 = Clk. 64 to 127 = Gate/Tap.
Pitch Bend Range	RPN 06	1 to 12
Local ON/OFF	122	0 = or 127

as a bonus, i also discovered the minibrute has similar parameter modification capabilities as documented in the MiniBrute Connection software editor manual ..

the macOS installer is also available further in that thread

i made a single attempt at installing the sound designer on macOS 13 with no success. 

met with error "the installer could not install the software because there was no software to install"

after some consideration i  will probably try it  on windows rather  than work this issue out.

this java GAIA tool seems very handy, but i am currently after something to mess with system settings so i am hoping the above does what i hope.

novation ZeRO SL MkII ROW SELECT

NOVATION ZERO SL MKII ROW SELECT BUTTONS DO NOT EXIST

There are multiple instances of the manual referring to the Row Select buttons, however these do not exist!!

Holding down [preview] then allows you to use the lower double row of buttons for the same effect.

--
"You can toggle the display format of the CC Num setting between decimal and hexadecimal by pressing the ROW-SELECT button for the upper left-hand row of buttons."

[preview]+[any of the upper double row buttons]

--

Template Grouping - "To step through templates within a group press any of the row select buttons multiple times."

[preview]+[any of the double row buttons] - slightly inconsistent behaviour, the first press does not cycle, but the second does. however after release only one press is required :?
