fellow weavers, the next macOS is supposed to run only 64bit apps if i understood that correctly. does that mean that rw5 wont run at all anymore in the near future? can you confirm this and maybe povide a workaround? thanks! ruby ---

If what you are saying about High Sierra is correct then yes RW will not run on it. Since v6 RW has been 64-bit only. However I believe that High Sierra will run some [limited 32-bit instruction](http://appleinsider.com/articles/17/06/07/high-sierra-runs-on-all-sierra-capable-hardware-starts-process-to-kill-32-bit-apps). It will however be the last MacOS to do so. RW5 is no longer supported so it will likely not run as it will not be fixed. I am sure @dan can fill you in with further details. ---

hi flash! thanks for your reply! i now googled some more detailed information on that and it seems that high sierra will still fully support 32bit apps. maybe even the macOS following high sierra 😉 so i can relax and sit back a little longer and use rw5 😉 also golive by the way…
