Security Update 2017-001 seems to have hung App Store Updates

hi all.

followed advice yesterday , tried install security update 2017-001.

clicked the 'install' button in app store updates last night 9.15pm, , twenty minutes later still showing 'installing-calculating' when had shut mac.

morning still shows same; 'installing-calculating', , think has become stuck somehow. (and may coincidental of course) mac has become incredibly slow morning, several second delay between keyboard , screen.

ideas please?

edit: sod's law has been applied... no sooner did post 2017-001 showing having been installed.

although, having said app store still endlessly 'checking updates' , showing 2 updates available on red badge in dock icon, 1 of had been security update, , mac still ever slow.

edit: security update showing having been installed twice in app store window, , running smoothly again. delete post if could.

 

reports there 2 or 3 builds of patch floating around. more people reporting installed 2x or 3x times.

patch appearently applies 10.13.0. maybe fixed file sharing issue ?
