We are now working on version 8.5 of Putty for Mac and have once again made some major progress the last couple months. We have added a copy & paste command to the CTRL+Right button mouse click menu. We have updated to latest putty git sources for this release. We have tested pageant, puttygen and plink and confirmed that everything is now working 100% correctly and as expected. Version 8.5 should be released later this month, until then here is some screenshots of our internal build.
