Hello everybody,

after some struggle, I was finally able to complete a jailbreak using a Mac computer. You really have to go an extra mile if you want to use a Macintosh, but you end up having a perfectly working Putty port on your mac.

My configuration is:

Code:

Nome modello:	iMac
  Identificatore modello:	iMac12,2
  Nome processore:	Intel Core i7
  Velocità processore:	3,4 GHz
  Numero di processori:	1
  Numero totale di Core:	4
  Cache L2 (per Core):	256 KB
  Cache L3:	8 MB
  Memoria:	20 GB
Versione sistema:      macOS 10.13.3 (17D102)
Versione kernel:	Darwin 17.4.0

This post explains how to prepare a mac for jailbreaking.
All this info relates to my personal experience.

How to prepare a mac for jailbreaking.

1. Install mac putty using these instructions here: https://onvinetech.wordpress.com/2016/01/26/49/
(note: this will also install python !).

2. Install the latest quartz release (you need X11 which is in there) https://www.xquartz.org/releases/index.html
Now if everything went ok, if you open a shell window and type putty the program interface should appear in an X11 window. Quit putty and go to step 3.

3. Now you need to find out which device to set for your serial communication. I was able to find it out using this instruction here: https://stackoverflow.com/questions/...-for-putty-mac.
(in my case: I used a “USB to TTL UART RS232 Isolated FT230 5V 3.3V 2.5V 1.8V” found on ebay https://www.ebay.it/itm/USB-to-TTL-U...EAAOSw7z1aK8A~ .
It is not the cheapest solution, but it is very handy as it auto-sets the working voltage and is an isolated board.
If you use this chip, you can download the mac drivers here: http://www.ftdichip.com/Drivers/VCP.htm)

Whatever chip you buy, make sure you also have access to its mac osx drivers

If you use this interface, after installing the driver on the mac, the correct configuration for mac putty serial device is “/dev/cu.usbserial-DM008AG7”. Remember this will only work if you use my very same chipset.

To enter this config select the “session” Item on the left part of the putty window. You then have to enter this driver next to the “speed” box in putty, which needs to be set to “115200”. It looks pretty much as it is shown here: https://www.mobileread.com/forums/at...8&d=1447624748, only instead of "COM3" you have to input your mac drivers's name.

That’s it, now you are done, your mac should now be ready for jailbreaking. If you connect the USB-to-TTL-UART-RS232 interface to an usb port on the mac and then press the “open” button in putty, a black text window should appear just like the one shown here: https://www.mobileread.com/forums/at...1&d=1447624770
