If you have access to a PC, you could download the Quark wallet and then just copy the wallet.dat file from your mac. Make sure to keep a backup.
An update, the recent dev wasn't up to the task of fixing the issue around the Superblock. We are currently working on finding a new dev.
I don't have access to a PC but I might be able to download a windows operating system onto an external hard drive to run on my mac. What and where can I find a windows wallet to download? It indicates "to come" on the first page of this thread just as it does for the mac version. Secondly, would you be willing to inform me as to where things stand it getting things fixed? Also, are there other people jammed up like this? How is trading being carried on. I simply want to have access to the Quark coin that I own. How is this supposed to be a viable cryptocurrency if it can't be accessed?
Thanks for your help in this matter.
