Dear @William Lisowski,
I also have a very similar issue on my Mac running Monterey 12.3 with Stata/MP 17.0?

Hi, there is any chance that you can upload the smoking.dta data set? Currently, I'm trying to use it as an example of synth as well and I only find another smoking dataset, that does not include the used variables. Thanks

Hey Belen Molina , do this

u "https://github.com/scunning1975/mixtape/blob/master/smoking.dta?raw=true", replace

This has the synth smoking dataset. If you want a fuller panel, use this

import delim "https://raw.githubusercontent.com/jehangiramjad/tslib/master/tests/testdata/prop99.csv", replace

but note that Jehangir's dataset doesn't include covariates
