UAD software v7.3 for Mac, featuring the API Vision Channel Strip plug-in, is currently unavailable. We have temporarily suspended its distribution based on a few isolated reports from Mac users experiencing crashes immediately after installation. These cases appear to be extremely rare, but we have removed the Mac download from the UA website out of an abundance of caution, until we determine the root cause of the crashes. Importantly, if you have already successfully installed UAD v7.3 for Mac, we have no reason to believe you will experience this issue. The crashes appear to only occur immediately after installation/system restart.
