9. AceThinker Online Screen Recorder
AceThinker enriches the market with its screen recorder software for desktop, as well as an online screen recorder service. For those who are reluctant to download program on Mac, this online streaming capture service is the very one they need. Yet, some would wonder why this convenient online screen recorder is placed at the last rank. Hold on! I can explain.
AceThinker online screen recorder is damn convenient, without program installation. However, when I test it by myself, the whole procedure is not so smooth as it claims. I was asked to download and install a launcher named Apowersoft Online Launcher after I click the "Start Recording" button on its webpage. I download and install it by its instructions. Yet, the launcher is not responding at all when I re-click "Start Recording" button after installation. I was asked to download this launcher again, again and again. But none of them worked.
I tried the old version (being re-directed to a new page indexed by "free-screen-capture"), no difference. Honestly, it didn't work. That made me wonder if AceThinker intended to guide users to download its desktop software. The online service might be just a gimmick. Certainly, AceThinker online screen recorder just didn't work for me, which didn't mean 100% failure in online screen capture. I just can't figure it out, totally making no sense. If you still wanna give it a try, I'd like to show you its user tutorial and wish you good luck. Now, you might understand why I put it at the last seat.
Step 1: Open your browser > head to https://www.acethinker.com/free-screen-recorder

Step 2: Tap the obvious "Start Recording" button and then you'll be asked to download its launcher.

Step 3: Install this launcher on your Mac. Afterwards, run it and then go back to the online webpage.

Step 4: Tap "Start Recording" button again to activate its online screen capture feature.
Step 5: Confirm the recording settings and begin to record what you need.
Step 6: Stop and save the recording to computer or directly upload it online.
