 Yeah I'm not a Mac OS user (Debian here), sorry about that and glad you
 sorted it out yourself!

 Got the new snowflake line.

 The snowflake line didn't work until I modified it to

 ClientTransportPlugin snowflake exec PluggableTransports
 /snowflake-client -url https://snowflake-broker.azureedge.net/ -front
 ajax.aspnetcdn.com -ice stun:stun.l.google.com:19302

 That's the way the original was, no ./TorBrowser/Tor/ at the beginning.

 ***

 Tried the bridges from bridges.torproject.org, six of them (i.e., since
 one gets 3 at a time, I downloaded twice), but could not connect. The
 built-in bridges for obfs4 work fine, but the ones from the database
 didn't. The captcha is very hard for me to read. With the letters and
 numbers overlapping, it's hard for me to be sure what it's asking for, and
 it usually takes me 3 or 5 tries. Not sure why the bridges aren't working.
 I downloaded some a few months ago, and they worked, but not today.

 @mwolfe: meek-amazon will also stop working since Amazon will deprecate
 domain fronting, so you should move to meek-azure and for snowflake
 replace the line with this latest one (from #22782):

 {{{
 ClientTransportPlugin snowflake exec ./TorBrowser/Tor/PluggableTransports
 /snowflake-client -url https://snowflake-broker.azureedge.net/ -front
 ajax.aspnetcdn.com -ice stun:stun.l.google.com:19302
 }}}

 Many thanks again to dcf for keeping up with this! :)

 That's because moat is broken too due to Google deprecating domain
 fronting. It will be fixed though in a next release(s).

 > Bridges used to be obvious on the Tor website, but I couldn't find a
 link when I looked, so I just click 'Select a built-in bridge', and this
 works fine here. After obsf4 stopped working, I'd click 'Select a built-in
 bridge' and choose meek, then when meek got slow, I tried obfs4, and it
 worked and was faster than meek.
 I'd recommend not using default built-in obfs4 bridges since they're
 public, you can however try out non-public obfs4 bridges by using meek
 first then going to https://bridges.torproject.org/bridges?transport=obfs4
 and doing the process to get obfs4 ones.

Comment (by mwolfe):

 The UAE has at least two ISPs. I see ads for Virgin, but I'm not sure if
 it's another ISP, or just a tool for one or both of the two I know. The
 two are du, which was used for your tests, and the other is Etisalat,
 eim.ae or etisalat.ae (that's the one I use).

 All the info about blocks was related to du, but the blocks would be the
 same for both (both du and Etisalat must run everything through the
 Telecommunications Regulatory Agency, or TRA). When du started, about 15
 years ago, it was only in Free Zones, and so didn't have any blocks, but
 then pressure to have two nationwide ISPs got du to offer Internet and
 phone services all over, and it got the same blocks Etisalat has always
 had.

 I'm glad someone was able to run the tests safely from a .ca account.

 Thanks for the link to the new snowflake. I'll try it and report later.

 Small tutorial on how to do that in case you don't know: (although someone
 should confirm if I didn't make any mistake)

 1. Go to your Tor Browser directory. Then go the folder `Browser` then
 `TorBrowser` then `Data` then `Tor`.
 2. Open the `torrc-defaults` using a text editor and change the snowflake
 line from
 {{{
 ClientTransportPlugin snowflake exec ./TorBrowser/Tor/PluggableTransports
 /snowflake-client -url https://snowflake-reg-test.appspot.com/ -front
 www.google.com -ice stun:stun.l.google.com:19302
 }}}
 to
 {{{
 ClientTransportPlugin snowflake exec ./TorBrowser/Tor/PluggableTransports
 /snowflake-client -url https://d3prdmp6d0elsl.cloudfront.net/ -front
 a0.awsstatic.com -ice stun:stun.l.google.com:19302
 }}}
 3. Save, and enjoy!

 Also by obfs4 you mean you got them from the BridgeDB or you used the
 default ones (in the dropdown menu when they ask which pluggable transport
 to use)?

Comment:

 Snowflake stopped working because Google blocked domain fronting to App
 Engine, which Snowflake uses for rendezvous: #25804.

 You can work around it by using the alternative domain fronts from #22782.

 See also #25594 about alternative rendezvous methods.

 Early in '17, Tor stopped working. Turned out, they'd turned on blocking,
 but obfs4 worked. Then obfs4 stopped, and someone suggested I try
 Snowflake, which worked back then. But Snowflake stopped working one day,
 and I learned it was alpha, and not well supported, so I switched to meek.
 Now I can't get Snowflake to work at all (Tor doesn't even load), but
 obfs4 is working again, and seems to work much better than meek.
