are you aware of the fact that macOS won't support 32 bit apps in near future? With High Sierra 10.13.4 you get a warning every time when you start a 32 bit app like iGetter.

Is it planned to release a 64 version of iGetter?

Thanks for the info. First, the alert should be shown only once for each 32 bit app.

iGetter engine can be made 64bit very easy, but the interface requires complete rewrite. I hope that our Mac developer will do it in time for the next macOS release, but can't promise that.

Actually, a 32bit app uses less RAM, but that's Apple decision and we have to comply. Currently, all large numbers in iGetter are 64bit, so there is no limit for the file size of your downloads for example. Finally, all iGetter extensions are already 64bit for compatibility with browsers.

Update - Apple issued a statement about 32bit apps

Most probably, you've missed some of the Apple 32 bit apps currently installed on High Sierra:
- DVD Player:

- iMovie launches the "Codec32bitTool_sb" 32 bit process:

- that activates the Ink System Preferences Panel at /System/Library/Input Methods/
- Core Virtual Machine Compiler at /System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/CVMCompiler

Some other 32 bit apps:
- Macs Fan Control (updated to 64bit)
- Ohanaware's Iconographer (requires macOS 10.10 and up)
- TextWrangler
- BBEdit (updated to 64bit)
- DragThing
- UPS driver of
- Fujitsu's ScanSnap
- Steam (Gaming software)
- The Uninstaller
- vmware-tools (VMware-Fusion 10)

Update 2018-06-20 - two apps of the list are now 64bit. But I found two new on my Mac: vmware-tools and "The Uninstaller":
Apple still ship 32-bit apps on macOS 10.14 and even promote TextWrangler on the new App Store presentation. They don't show any 32bit warnings for their apps though.

MacsFanControl is 64 bit since the last three updates or so.

On my system iGetter is the only 32 bit app and unfortunately the only app that causes often more than 100% cpu utilization.

iGetter is the best download manager for the mac but it's behind time. I hope we will get an update soon.

100% CPU load is unusual. I see that you have a long record of complaints for high CPU load. The last thread was related to corrupted fonts on your machine:

Without an Activity Monitor Sample of iGetter, we can't determine what causes the problem in your particular case.

iGetter is one one of the few apps on my Mac that uses very little resources while downloading (~10% CPU and 20MB RAM) and practically there is no CPU load when idle. The only case when iGetter uses more CPU for a brief period (Activity Monitor shows about 80% CPU/20MB RAM) is when it calculates MD5 and SHA1 checksums at completion. But iGetter never goes unresponsive even in those moments.

Just now 467 % CPU workload by iGetter while downloading 2 files. Not bad on an i7.

Odd! iGetter works for me for years and never goes above 20% CPU while downloading (usually ~10% CPU).

In order to find what's wrong, please send a public download link and a Sample of iGetter created in Activity Monitor to .

Some hints for good performance:
- turn off Anonymizers and VPN applications.
- download on internal or external HDDs, but not on NAS/AFP volumes.
- set "Max simultaneous downloads" to 2 and "Default number of segments" to 4 (at iGetter Preferences > General and Acceleration panels)
- check for corrupted fonts (showthread.php3?threadid=1636)
