• Various fixes for running the extra tools as a non admin user.

v16-6-2024

16-6-2024

• display BootNext, unnamed, clover and gpu-power-mode variables

• logging of Board-ID for iMacPro 1,1 and MacPro 7,1

• logging detailed csr config status

• -hexdumpall argument for test_nvram
  with test_nvram dumpfile.bin -hexdumpall a full list of hexdumps of deleted and valid NVRAM variables is displayed. This can be hughe.

• additional tool: Macschrauber's System Version Scanner
  it scans thru all mounted volumes and displays the MacOs version, drive and physical position, similar to the ESP tools.

• ESP tools:
  Also various corrections and additions to the ESP tools, regarding Windows ESP and external volumes.

v5-5-2024

5-5-2024

• presenting CSR values for s.i.p / rootless flags
  like: csr_Allow_Untrusted_Kexts, Unrestricted_FS, Task_For_Pid, Apple_Internal, Unrestricted_Dtrace, Unrestricted_NVRAM (0x77)

• warn for unusual var headers
  like state: 0x00 or 0xff and size: 0xff

• presenting nvda_drv=1 variable

• presenting efi-boot-device-data variable

• the log shows a platform compatibility test for the helper tools

fixed: security mode=none presented an alarm, tho this setting is useless it must not show a warning

• ESP tools:
  added: OCLP got the model in the string
  fixed: did not wrote an icon for Windows ESPs, also added support for multiple ESPs on one volume.

v21-4-2024

21-4-2024

• analyzing .scapfiles

• revisited the display of the NVRAM variables to
  example: 1 (5 deleted) MemoryConfigg

• showing some more NVRAM variables:
  recover-boot-mode
sleepwake_diagxx
SleepWakeFailureString
StartupMute and
  SystemAudioVolume for detecting no audible boot chime

• wildcards for the test_nvram_shell script. Like test_nvram *.bin -showallvars

• multiple CRC32 errors got all UUIDs displayed

v31-3-2024

31-3-2024

• added an option for ESP Mount from list and show bootloaderto prevent booting of Uefi Windows
  If started on a Mac Pro 1,1 to 5,1 unit it allows the user to rename bootx64.efi to bootx64.efioff to
  prevent direct booting Uefi Windows without OpenCore / RefindPlus protection.

• a 2nd variant of the LBSN Sector for MP41 is detected

• -nofreshdump argument for test_nvram and adding this for analysing ch341a dumps
  As a readout of a chip in the programmer could not be treated same for live diagnostics.

also a fix for Type_80 firmwares what have more than one Fsys stream in the NRAM Volume, reporting FSys variables order

v22-3-2024

22-3-2024

• analysing .dump files eficheck creates for sending them without user data (Fsys stream) to Apple
  My Mac Mini 7,1 creates a 6 MB file, I would need more examples of other sizes

• the stop button of the progress window works now in the Dumper and most of the tools

• worked over a handler to process sudo cli tool calls, so more precise logging

• added download from github to the downloaders

Also error correction in the Is damaged fix tool due to a typo in a version comment.

v2-3-2024

In V2-3-2024 a glitch was fixed when the font "Courier New" was missing it prevents displaying the analyse dialog.

v19-10-2024

changelog for v19-10-2024

The Dumper:

• detects if running on a T2 or Silicon Mac and removes the button accordingly.
• added a dialog for missing LBSN/BD sector.
• decodes board-id to Mac model in log file.
• tells the user if the assigned FireWire address does not match the firmware MAC address.
  This may indicate that on an MP41 or MP51, firmware from another machine was flashed.

test_nvram:

• dumping IM121 is forced to use eficheck (available from High Sierra to Ventura) due to a crash when loading DirectHW.kext.
• "FW MAC matches not with LBSN" or "FW MAC matches with LBSN" line, when the Mac has Firewire and LBSN sector has a firmware MAC address.
• a catch when Eficheck is not available (before 10.13, after 13).
• a catch for an empty EFI version string
• CRC32 check for the main firmware volumes for MP41 and MP51 firmwares.

Macschrauber's System Version Scanner:

• more sealed status report.
• more progress bar steps for multiple MacOS on one machine.

Wifi-Scripts:

Select Wi-Fi from found networks and Select Wi-Fi from preferred networks:
Message and workaround if Airport Utility cli tool is not working anymore on OS since Ventura.

ESP Tools:

• detect amdvbflash ESP

unmount all ESPs, Mount ESP from list, Mount ESP from list and show bootloader:

• unmounting has an option to handle busy status of ESPs.

copy ESP:

• sets script into a loop, to work on more than one ESP in a row.

Boot-Args:

• edit boot-args got into a loop, so editing more options is more comfortable.

Preboot Fixer:

• mount ESP needs admin privileges if user is not in admin group, fixed when using stored admin / password data.
