alesis multimix 16 firewire on Sierra and above?

the drivers do not install on more recent macOS versions.

you can disable a particular security setting to allow installation, then the device works correct!

in terminal

csrutil enable --without kext

and reboot

to re-enable

crsutil clear

bootable USB macOS sierra - not a valid volume mount point

the basic technique of using

/Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia to create a USB installer drive fails with error

"not a valid volume mount point"

Simple work around is to modify one string inside a file inside the macOS Sierra.app

sudo plutil -replace CFBundleShortVersionString -string "12.6.03" /Applications/Install\ macOS\ Sierra.app/Contents/Info.plist

I did it manually by going into app and opening info.plist with textedit.

update restore iphone to specific old version of ios

 when you connect the phone to itunes

OK THAT DIDNT WORK AT ALL LIKE INTENDED .... WILL UPDATE LATER MAYBE

thanks to some random post on the internet (i cant find now) for this help.

Dell BIOS update workaround with no battery.

DELL XPS L501X with no Battery running an old BIOS.

tl/dr
extract bios from official release, phlash it from DOS.
...

running the official Bios phlasher fails because I dont have a battery.
error given -144
to sucessfully use the official phlash the laptop needs to be running off AC AND have battery plugged in.

when this fails it does however usefully extract the bios wph file,
in my case to
/USER/AppData/Local/Temp/WinPhlash64/BIOS1.WPH

USER is my username, which will vary on different systems, and you will also need to view hidden files and folders as Local is invisible.

-- now you need a bootable USB-stick to run DOS,
i used RUFUS https://rufus.ie
-- next a DOS version of WinPhlash
i used version 1.7.0.21 https://www.wimsbios.com/phoenixflasher.jsp

-- copy PHLASH16.EXE to the USB drive.
-- copy BIOS1.WPH and rename as BIOS.WPH to USB drive

-- reboot into DOS,
run PHLASH16.EXE

it beeps a lot and loudly, then is finished !!

** dont forget fucking up the BIOS can brick your laptop **

virtualising raspberry pi.

seems trick is because pi uses ARM processor, need to use QEMU virtualiser.

the basic requirements are
QEMU
kernel to emulate physical environment
OS img to run

tips. 


change screen resolution for gui.

sudo nano /etc/X11/xorg.conf

Type the following into the file you have just created:-

Section "Screen"
Identifier "Default Screen"
SubSection "Display"
Depth 16
Modes "800x600" "640x480"
EndSubSection
EndSection

change VM img/HDD size.

qemu-img.exe resize 2015-02-16-raspbian-wheezy.img +10G

when you run the OS, you will then need to "Expand Filesystem" to fill entire image, else you will only have access to the size of the original img
this is done in the Raspberry Pi Software Configuration, which should open on initial boot up, then reboot.
to access configuration

sudo raspi-config

(see
https://www.pcsteps.com/1199-raspberry-pi-emulation-for-windows-qemu/)


change swap size from default 100mb

sudo nano /etc/dphys-swapfile
change to whatever. to restart swap file, can reboot or

sudo /etc/init.d/dphys-swapfile stop
sudo /etc/init.d/dphys-swapfile start
