    Nitpick: this should go after #include <QAbstractNativeEventFilter>

src/plugins/osx/macpoller.h (line 75)
<https://git.reviewboard.kde.org/r/126078/#comment60678>

    One line per variable.

src/plugins/osx/macpoller.h (line 76)
<https://git.reviewboard.kde.org/r/126078/#comment60679>

    Here too.

src/plugins/osx/macpoller.cpp (line 2)
<https://git.reviewboard.kde.org/r/126078/#comment60664>

    This should be appended to the list, not prepended. I know, the next line is \
wrong too.

src/plugins/osx/macpoller.cpp (line 29)
<https://git.reviewboard.kde.org/r/126078/#comment60665>

    Remove trailing space character.

src/plugins/osx/macpoller.cpp (line 49)
<https://git.reviewboard.kde.org/r/126078/#comment60677>

    Initialize m_nativeGrabber here too.

src/plugins/osx/macpoller.cpp (line 100)
<https://git.reviewboard.kde.org/r/126078/#comment60681>

    Use qCWarning instead.

src/plugins/osx/macpoller.cpp (line 135)
<https://git.reviewboard.kde.org/r/126078/#comment60666>

    Shouldn't you check the return value of this method?

src/plugins/osx/macpoller.cpp (line 137)
<https://git.reviewboard.kde.org/r/126078/#comment60667>

    This should be changed to "return true", right?

src/plugins/osx/macpoller.cpp (line 212)
<https://git.reviewboard.kde.org/r/126078/#comment60669>

    We usually join the last } with the next "else {", like this:

    } else {

src/plugins/osx/macpoller.cpp (line 221)
<https://git.reviewboard.kde.org/r/126078/#comment60668>

    Remove commented code.

src/plugins/osx/macpoller.cpp (line 242)
<https://git.reviewboard.kde.org/r/126078/#comment60670>

    We usually do not use extra space after ( and before )

src/plugins/osx/macpoller.cpp (line 274)
<https://git.reviewboard.kde.org/r/126078/#comment60671>

    Remove commented code.

src/plugins/osx/macpoller.cpp (line 325)
<https://git.reviewboard.kde.org/r/126078/#comment60672>

    I do not get the "Unsetting m_catch is enough" comment. What is it supposed to \
mean since unsetting m_catch is the original code.

src/plugins/osx/macpoller.cpp (line 343)
<https://git.reviewboard.kde.org/r/126078/#comment60673>

    Remove trailing space and shouldn't the commented code in this method be removed?

src/plugins/osx/macpoller_helper.mm (line 2)
<https://git.reviewboard.kde.org/r/126078/#comment60674>

    Append new entries in copyright section, do not prepend.

src/plugins/osx/macpoller_helper.mm (line 43)
<https://git.reviewboard.kde.org/r/126078/#comment60680>

    Use qCDebug instead.

src/plugins/osx/macpoller_helper.mm (line 54)
<https://git.reviewboard.kde.org/r/126078/#comment60676>

    Usually when a new operation returns 0 it is because system is on short on RAM \
memory (or memory is too fragmented). I would add assert here instead of silently \
ignoring the failure to allocate memory.

src/plugins/osx/macpoller_helper.mm (line 78)
<https://git.reviewboard.kde.org/r/126078/#comment60682>

    There is no point in doing this if the next line will delete nativeGrabber.

src/plugins/osx/macpoller_helper.mm (line 82)
<https://git.reviewboard.kde.org/r/126078/#comment60675>

    This line can go to inside the if clause above.

application waits forever, without ever getting to compare idle time to the list of \

this doesn't happen on Linux.</p> <p style="padding: 0;text-rendering: \
