This new update addresses the following, as noted by @planetbeing:
v0.2: Tries to fix no reboot after activating VPN/tapping Absinthe icon. We also tried to fix white icons on SpringBoard after jb.
He also goes onto mention why Absinthe can take a while to jailbreak:
The jailbreak partially relies on making backups. If you have 5 GB of app data, don’t be surprised it takes long to transfer 15 GB of data.
Should you re-jailbreak with this updated version of Absinthe for Mac if the first time was successful? @planetbeing says no.
Users had issues yesterday with Absinthe for Mac as activating the VPN would not force an automatic reboot. Also, users had reported of seeing white icons after the jailbreak. This version should alleviate those issues you might have experienced.
Let us know how it works for you!
