Note: The primary macOS version is for those using 10.10+. If you are using 10.6.8+ then use the legacy version available from https://syncplay.pl/Syncplay_1.5.3a_macOS_legacy.dmg
Note: This open source software has been marked as clean by Jotti (.exe, .zip, .dmg, legacy .dmg) and VirusTotal (.exe, .zip, .dmg, legacy .dmg). Syncplay might be flagged as suspicious by some anti-malware systems simply because it is niche software downloaded from the Internet but as we are open source anyone can audit our code if they wish to do so.
