Frequently asked questions
What is the latest Slack desktop version?
Slack's official Windows release notes list version 4.50.143, released June 23, 2026. Mac and Linux builds can use different version numbers and rollout timing.
Does Slack support Windows ARM64 and Apple silicon?
Yes. Slack provides current desktop routes for Windows ARM64 and for Apple-silicon Macs alongside conventional x64 Windows and Intel Macs.
Can I install 32-bit Slack for Windows?
No current 32-bit release is listed. Slack moved its Windows desktop releases to 64-bit, so What-Version does not route x86 Windows devices to a current package.
Why can Slack's supported operating systems change?
Slack follows an operating-system lifecycle and periodically ends support for older Windows, macOS, and Linux releases. Check Slack's official requirements if your system is near an end-of-support date.
