@mdboom is this still a thing with the new osx backend?

@SPike666 Can you provide any more context for this change? What warning were you getting?

@tacaswell I was working with biosppy python module (toolbox for biosignal processing, https://github.com/PIA-Group/BioSPPy) which uses matplotlib to visualise processed data.
On calling ecg.ecg(data, sample_rate, draw=True) function, matplotlib was throwing warning in tight_layout.get_renderer function (UserWarning: tight_layout : falling back to Agg renderer
warnings.warn("tight_layout : falling back to Agg renderer"))
which was caused by canvas that had no attribute/method "get_renderer". I've set breakpoint and saw that canvas has "renderer" attribute - added elif statement and it worked fine.
All the code after that warning wasn't executed but there were no exceptions - maybe the module handled it. It was performed on Macbook Pro with OS X El Capitan v.10.11.4 with Python 2.7.10

As far as I know this has been fixed on 2.x as part of #6178 see 142d9fc

Closing this as on 2.x/master the macosx backend does have a get_renderer method. That would be the preferred solution (making the macosx backend compliant with everything else rather than adding a special case for it).

@SPike666 Please ping to have this re-opened if you are still getting these warnings using either 2.x or master.
