On macOS, arm64, and universal binaries

January 5, 2021January 5, 2021 Chris Cannam

A handful of notes I made while building and packaging the new Intel/ARM universal binary of Rubber Band Audio for Mac. I might add to this if other things come up. See also my earlier notes about notarization. Context I'm using an ARM Mac – M1 or Apple Silicon – with macOS 11 "Big Sur",… Continue reading On macOS, arm64, and universal binaries

On macOS “notarization”

February 12, 2020February 17, 2020 Chris Cannam

I've spent altogether too long, at various moments in the past year or so, trying to understand the code-signing, runtime entitlements, and "notarization" requirements that are now involved when packaging software for Apple macOS 10.15 Catalina. (I put notarization in quotes because it doesn't carry the word's general meaning; it appears to be an Apple… Continue reading On macOS “notarization”

How to change your friend’s OS/X Yosemite system font to Arial

January 19, 2015January 19, 2015 Chris Cannam

Apple made a lot of visual changes in release 10.10 ("Yosemite") of Mac OS/X. One of the most obvious was to change the system font, as used throughout the desktop, from Lucida to Helvetica. A lot of people love Helvetica, so presumably they were happy. Others were less satisfied, leading to a little rush of… Continue reading How to change your friend’s OS/X Yosemite system font to Arial

Single-key menu shortcuts with Qt 5 on OS/X

June 3, 2014June 3, 2014 Chris Cannam

Several of my Qt-based applications, including Sonic Visualiser and Tony, have some menu actions attached to single-key shortcuts without a modifier key. Examples include the Space bar to start and stop playback, or the "f" key (without Ctrl, Alt or any other modifier) for zoom-to-fit. While testing the update from Qt 4 to Qt 5.1… Continue reading Single-key menu shortcuts with Qt 5 on OS/X

What laptop, tablet, or smartphone to buy? It’s a complicated business

January 6, 2013January 6, 2013 Chris Cannam1 Comment

My Dad asked me recently what sort of computer he should buy to replace his ten-year-old HP laptop. And what sort of phone should he get to replace his old Nokia? And while I was at it, should he get one of those tablet things? There are a lot of possible options at the moment,… Continue reading What laptop, tablet, or smartphone to buy?

Can you develop research software on an iPad?

December 5, 2012December 5, 2012 Chris Cannam

I've just written up a blog article for the Software Sustainability Institute about research software development in a "post-PC" world. (Also available on my project's own site.) Apart from using the terms "post-PC", "touch tablet", "app store", and "cloud" a disgracefully large number of times, this article sets out a problem that's been puzzling me… Continue reading Can you develop research software on an iPad?
