Test run the macOS Sierra public beta and alert Apple about bug fixes

Caught up with some MacWorld reading and it seems the macOS Sierra public beta was released in early July. Want to be a test pilot? Sign up to the Apple Beta Software Program with your Apple ID. You can sign up for both macOS and the iOS.

This public beta software is confidential, so you can’t share any information about it except to send reports directly to Apple with the built-in Feedback Assistant app.

As this is pre-release software, you should not try this on your workhorse mac. Some applications may not be ready for macOS Sierra, but some will have public betas ready, which they hope to recruit feedback for as well.

This sort of exercise has solved many problems I have had over the years with various software so I am glad to see this happening again.

If you have been dying to try out macOS Sierra, want to put it through its paces, want to help iron out conflicts for a smooth ride eventually, and can’t wait for the official release in a couple of months, then sign up here.

How to get the macOS Sierra beta

‘When to enhance audio?’, the soundman asked me – screen grab annotations with Skitch 1.0.12 to the rescue!

I was giving a talk at a venue which had a tech guy controlling audio from the sides. the crowd was noisy gabbing away over dinner so I needed the subtle vote overs to be heard. But we could not keep the volume up as that generated feedback noise. The soundman wasn’t sighted well enough to respond quickly when the slides flashed by. And I had just turned up so there wasn’t time for him to get familiar.

Well, a prompt would be helpful.

My videos were embedded on a dark background so I switched keynote to lightbox view, did a screen grab with Skitch 1.0.12 and circled the videos – they were obvious in the lightbox view but circling removed any doubt. I dragged and dropped the the image to the USB drive which dangled from my keychain and he was relieved. Now we were in business.

Well we started minutes later and managed a very smooth delivery indeed, and kept to time too! We exchanged a satisfied thumbs up to each other when it was over.

I made a point of citing the version – Skitch 1.0.12, because it is this 2012 version which was well loved by many [download link (11.9MB)]. Subsequently, Evernote bought over Skitch and completely ruined a lovely tool (e.g. see here and here)!

Ver 1.0.12 is still my favourite screen grab and annotate tool. It still works in OSX 10.11 El Capitan but I looked around for Plan B, just in case and YellowMug’s SnapNDrag Pro is not bad.

Update your Mac hardware – phone, laptop, watch, tv etc (18 Jul 2016) & OSX El Captan 10.11.6 Combo Update

There was a bug alert it seems, so do update your Apple products to OS X El Capitan v10.11.6, iOS 9.3.3 and the tv and watch OS’ too, with the latest OS releases – check your device settings if you have not been prompted as yet, or your App Store Updates tab.

Although the published date for the updates were from three days ago, I had not been prompted by my phone or laptop. Instead it was a friend on twitter who alerted me.

I apply an update when it comes these days, and am no longer the cautious wait and see guy.

But I hunted for the preferred combo update, which does not easily surface early in a google search during a release. So I checked one of the online mac magazines and found it the link.

Penned this reminder when a Mac user asked me, what release?

Join me in celebrating National Day with a coastal cleanup @ Lim Chu Kang beach and mangrove!

In 2008, I was dismayed to see the amount of plastic and other trash that had accumulated on the lovely patch of mangroves at Lim Chu Kang – this was one of the first mangroves I had mapped as an undergraduate with Paddy Murphy and a site I spent many days and nights at.

I decided I could not wait for the annual International Coastal Cleanup Singapore (ICCS) in September so initiated a cleanup. The next year, I shifted the cleanup to early August in celebration of National Day where it also heralded in the start of the academic year and an extremely hectic semester at the National University of Singapore. We usually remove more than half a tonne to a tonne of trash.

This 9th year of the cleanup, we will be working on Saturday 6th Aug 2016: 8.00am – 10.30am. To join us, sign up here by 1st August 2016! Transport will be provided from Kranji MRT to the cleanup site @ Lim Chu Kang beach and mangrove. Details on the ICCS blog.
