Flume.
The IDM you missed, made for the Mac.
If you used Internet Download Manager on Windows, Flume is that for your Mac. It catches downloads from your browser, splits each file across many connections, and saves video from the page you’re on. Pause, quit, lose Wi-Fi: it picks up where it left off.
What it does
Everything a download manager should do. Nothing it shouldn't.
Up to 32 connections
When one part finishes, its connection takes over half of the biggest part left, and Flume adds connections only while they make the download faster.
Faster on bad connections
When a file can only come over one connection, Flume uses HTTP/3 if the site supports it, which keeps speed up on slow or lossy routes. It follows your Mac’s proxy settings too.
Resume anything
Survives quitting, crashes and network loss, and pauses by itself when your Mac goes offline. If the file changed on the server, Flume starts over instead of saving a broken file.
Works with your browser
A small extension for Chrome, Brave, Edge, Arc and Chromium hands downloads to Flume. Right-click to grab every link on a page, or just the ones you selected. If Flume can't take one, the browser carries on as usual.
Downloads that need a login
Your browser's sign-in travels with the download, so files behind a login, like a spreadsheet's Download a Copy, just work.
Save videos
A Download button on videos, with a choice of quality or audio only. Works on YouTube, Vimeo, TikTok, Instagram and sites you're signed in to. Live streams aren't supported.
Queues, limits and schedules
Run several queues, each with its own limit, active hours and days. Cap speed overall or per download, or cap data per time window.
Finishes, then sleeps
Tell Flume to quit, put the Mac to sleep or shut it down once everything is done, with a countdown you can cancel.
Tidy folders
Finished files sort themselves into Video, Music, Documents and more. Progress lives in the menu bar too.

Questions
- Is Flume like Internet Download Manager (IDM)?
- Yes. Flume does for the Mac what IDM does on Windows: it catches downloads from your browser, splits each file across up to 32 connections, resumes after a crash or network loss, and saves video from the page you are on.
- Which browsers does Flume work with?
- Chrome, Brave, Edge, Arc and Chromium, through a small extension that Flume sets up for you. Firefox works as a temporary add-on that has to be loaded again after Firefox quits.
- Can Flume download videos?
- Yes. A Download button appears on videos, with a choice of quality or audio only. It works on YouTube, Vimeo, TikTok, Instagram, X, Reddit, Twitch, SoundCloud and other sites, including ones you are signed in to. Live streams are not supported.
- Is Flume free?
- Yes. Flume is free, with no ads, no account and no tracking.
- Which Macs does Flume run on?
- Macs with Apple silicon running macOS 14 or later.
