Mac users planning to upgrade to Catalina, the latest version of Mac OS, will not be able to use the desktop version of uTorrent. Both uTorrent and BitTorrent Mainline are not compatible with the new operating system, and users are automatically upgraded to browser-based "Web" clients.
uTorrent for Windows first came out in September 2005. Soon after, it became the most widely used torrent client, as it still is today.
Originally, Apple users were left out, but after three years BitTorrent Inc. released its long-awaited version of Mac OS.
While official numbers are not available, uTorrent probably never got the impressive market share it enjoyed on Windows. This is partly because there were already several established Mac torrent clients around, including Transmission and Vuze.
In recent years there has been very little progress on the Mac development front. The latest client update goes back to last year, and there are virtually no discussions going on in the official Mac forums. It was also excluded from the recent release of BitTorrent Speed, which is Windows only.
That said, something big is expected next month. BitTorrent Inc. just announced that the desktop versions of uTorrent and BitTorrent Mainline will not be available on the new Mac OS Catalina (version 1
The reason for this is quite simple. uTorrent Mac is only available as a 32-bit application, while Apple's upcoming version of Mac OS Catalina is only compatible with 64-bit apps.
“Therefore, in early September, we will automatically update µTorrent Classic for Mac to our latest torrent downloader and player, µTorrent Web for Mac. This is necessary to ensure that the torrent download software continues to work seamlessly with Catalina as millions of users update to the new version, announces BitTorrent Inc.
"We will start updating users in early September. If you use µTorrent Classic for Mac version 1.87 or earlier, you will automatically be upgraded to µTorrent Web for Mac. "
It is no surprise that support for 32-bit applications will end up on the newer Mac OS. This has been known for some time, and off for this reason, a 64-bit version of uTorrent was added to the list of features last year, but that request received no official response.
As a result, all users of the new Mac OS Catalina will have to move their torrenting- browser activity, or find an alternative client. Users who have not updated Mac OS to Catalina can continue to use the desktop version
