Using v25.4.1 on a machine connected to the internet—especially one with sensitive files—is risky. . Never download or run “cracked” versions of this software, as they are likely to contain these unpatched exploits or additional malware.

Based on the capabilities of that era, here is a standout feature introduced during the 2021 release cycle: Rotatable Canvas

While Illustrator 25.4.1 was released before full native Apple Silicon optimisation was complete, it could still run on M1 Macs via Rosetta 2 emulation. However, some community reports suggest that version 25.4.1 had limited compatibility with M1 systems at the time. For the best experience on modern Apple Silicon hardware, later versions (25.4.2 and beyond) introduced native M1 support with significant speed improvements. If you are using an M1 or M2 Mac today, consider updating to a newer version that fully supports Apple Silicon. As Adobe has stated, “Illustrator now runs natively on Apple computers using the Apple silicon M1 chip with 1.5X the speed of similarly configured previous generation systems” in subsequent updates.
